5 1 Introduction The UltraZed-EV Carrier Card (CC) is a development board designed to be used by customers for rapid proof-of-concept and prototype development efforts using the Avnet UltraZed-EV System On Module (SOM) module(s). Leveraging the Carrier Card and SOM solution greatly reduces time to market and hardware risk by increasing target application development time on a proven reliable hardware platform. Further, the design files for the carrier card are made readably available to customers, allowing a direct design copy of what is proven to work. This carrier card provides all of the necessary SOM power, clock, reset control and SoC I/O pin accessibility through the JX1, JX2, and JX3 MicroHeaders and also includes multiple industry standard interfaces. The carrier card also provides two debug interfaces - SMT2 (Micro USB) and PC-4 JTAG header. The SMT2 interface requires a micro USB cable. The PC-4 requires a debug module such as the Digilent HS3 dongle. Both interfaces are provided to assist with SOM application development. This document details the specific features, operation and configuration of the UltraZed-EV CC board. Please visit For the latest product information.

11 2.2 PS USB 2.0/3.0 Interface J17 The UltraZed-EV Carrier Card s USB 2.0/3.0 interface is implemented with a Kycon KMMX-AB10- SMT1SB30TR Micro AB connector capable of supporting OTG, Device and Host modes. The UltraZed-EV SOM contains the USB 2.0 ULPI PHY interface (USB3320 IC) for USB 2.0. PS GTR[2] is used to implement the USB 3.0 interface to the same connector USB 2.0 Interface a. The USB 2.0 interface is connected via the SOM s ULPI PHY IC. b. The interface differential impedance is 90 Ω (+/- 5%), Single Ended is 45 Ω (+/- 5%) c. Power: 5V, 500mA. d. CPEN is used to enable the ACPI/USB compliant Microchip MIC2544_1YMM high side switch IC. When CPEN is logic high, enabled, the +5.0V rail is passed through to the +USB_VB rail for the USB connector. e. When CPEN is low the power switch is disabled. f. R102 is used to set the current limit of the MIC2544 part. The value of 191 ohms is used to set the current to 1.23 Amps. g. When in Host or OTG mode, FB8 and FB9 along with two capacitors are used to provide filtered power to the USB connector J12. h. D42 ESD suppression array protects the USB_OTG_P/N signals. i. LED D40 is used to indicate a current limit or thermal shutdown event with the MIC2544 IC. The output is open-drain and asserted low when a flag event has occurred which causes D24 to turn on. The output is not latched and therefore clears once the event ends thereby extinguishing D Device, Host or OTG mode select jumpers JP21, JP22, JP23 a. J22 selects how the USB_ID net is connected. Pin 1 to 2 allows the USB device to connect to the SOM, pin 2 to 3 forces the pin to +3.3V. No populate allows the pin to float. When floating the interface is set to Device mode but once connected the operation can be reversed via the Host Negotiation Protocol (HNP). By default the jumper is not populated. Figure 2 JP22 USB_ID select jumper b. JP12 is used to select the power for +USB_VB. c. JP21 used to select the pullup resistor for the USB_OTG_VBUS net going to the SOM. d.

18 2.5 PS SATA 3.0 Host Interface J6 The UltraZed-EV Carrier Card s SATA 3 host interface uses the SoC s PS GTR[1] transceiver. The interface includes AC coupling capacitors with appropriate PCB GSSG cut-outs and a maximum of 2 layer transitions per signal with no blind or buried vias. This topology is used to minimize impedance mismatches thereby improving signal integrity.

19 2.6 PS PMOD Header JPS1 The PS PMOD header is connected to the PS MIO[36:43] pins and operated at 3.3V I/O using the VCCO_PSIO_501 rail. The PS MIO[36:43] maps to SPI, however the UltraScale+ does not create a direct map to the UART(0 or 1) nor I2C MIO pins. Table 9: PS PMOD to MIO UltrZed SOM Table mapping shows the UART and I2C connections. Routed at 50Ω single ended. The interface follows, as close as possible, the Digilent SPI and UART/I2C pinouts.

20 2.7 PS Micro USB Connector (Dual USB-UART Ports) J16 The dual USB UART port is via a microusb connector. The PHY interface IC is Silicon Labs CP2105 dual USB-UART device. The port has been configured for persistence, allowing the device to remain enumerated even when the Carrier Card s power is turned off. USB 2.0 compliant with royalty free drivers available for download. VDD and VIO are attached together to provide a persistent USB connection. When a host PC is attached, VBUS is used to generate VDD. No other board power is needed for the UART to be turned on. When the board is in the powered off state, no +3.3V is present so suspend LEDs D37 and D39 will not turn on until the board is powered on. Port 0 is connected to Bank 501 PS MIO[34:35], RXD, TXD and are level translated via MOSFETs. These signals are swapped on the carrier creating a null-modem connection. This allows a straight through cable connection. Port 1 is connected to Bank 501 PS MIO[32:33], TXD, RXD and are level translated via MOSFETs. These signals are swapped on the carrier creating a null-modem connection. This allows a straight through cable connection. GPIO signals or Modem control signals are not used and are brought out to a test pad for user convenience. LEDs: D37 and D39 indicate when the device is in suspend mode. By default the pins are active low during a suspend state. These pins are user programmable, and if desired, the polarity can be reversed allowing the LEDs to be on during normal operation and extinguish during suspend. Please refer to the Silicon Labs CP2105 datasheet for further information. The UART reset pin has an RC time delay from power up. This pin is also be controlled by the SOM s CC_RESET_OUT_N signal. A Vendor ID (VID) is not programmed into the OTP ROM. The device uses the default VID provided by Silicon Labs. A unique PID (Product ID) can be programmed in via the USB interface by the user. To accomplish this, a 4.7uF cap is required between NC/DCD_ECI/VPP pin and ground as shown below. Upon completion of programming, the capacitor should be removed. ESD device D38 is used on the USB D+ and D- lines for ESD protection. Impedance is 45Ω single ended control, 90Ω differential. Figure 14 PS PMOD interface Page 20

The interface operates at 3.3V. Since microsd cards do not have a Write-Protect (WP) pin, the PS SD controller SD_WP signal (MIO[44]) must be pulled up to the 3.3V rail to choose Write Protect via JP2. When JP2 is not populated, SD_WP is grounded via R40 on the UltraZed-EV Carrier Card. JP2 WP Jumper used to allow Write Protect emulation for microsd cards if needed. The default position for this jumper is Not Placed, thereby disabling Write Protect function. The interface is routed at 50 ohms single ended.

Figure 16 PS User LED 2.10 PL User Switches Slide DIP & Push Buttons SW1-SW5 The Carrier Card has 12 PL user switches. Four pushbutton switches SW1-SW4, and an 8 pin DIP slide switch, SW5. SW1 SW4 pushbutton switches are normally open when not depressed and are pulled low via RP1, a 10K resistor pack. When SW1 SW4 are depressed, they provide a 1.8V signal via 240 ohm pull-up resistors. 0.1uF capacitors are placed to minimize switch bounce noise. When slid to the ON position, SW5 outputs are pulled high to a logic level of +1.8V via a 240 ohm current limiting resistor pack. When in the OFF position (open), SW5 outputs are pulled low via a 4.7K resistor pack. Figure 17 PL User Push Button switches Page 22

See Table 24: U3 Clock 1 boot configuration table for the other jumper configurable frequencies. To configure using software, the device must be accessed via the I2C bus and configured each time the board is powered on. Mode 0 is the default frequency selection when the board is manufactured. Mode 0 jumper positions are as follows: JP1, JP16 and JP17 not placed. The IDT device has weak internal pull-down resistors on these pins. I2C software configuration mode: the user can configure the IDT part using the I2C bus. To configure the IDT part for different frequencies, JP16, JP17 jumpers must be placed at positions 2 3 and jumper JP1 removed. Figure 44 U3 Clock Synthesizer configuration jumpers Page 45

This signal can also be driven by the PC4 JTAG Header (JTAG_INIT) pin and the GPIO2 port on the SMT2 module through zero ohm resistors. This signal can be used to reset the MPSoC device as well as all other devices on the UltraZed-EV SOM via the JX1 connector. The SOM_RESET_IN_N is an active low signal and when not active is pulled up to +1.8V on the SOM.

The signal is driven from an open drain circuit on the SOM and therefore does not require voltage isolation. This signal resets U6, the IDT GTH Clock and also turns on a red LED indicator.

The board has a SMT2 USB module, a PC4 header and the FMC interface that are all chained together on the carrier card. Further, a jumper and translator is designed in to allow JTAG FMC access. The FMC JTAG is operated at +3.3V, while the Carrier Card s JTAG is at 1.8V, thereby the FMC JTAG connection has a signal level translator. When using the SMT2 module, the interface only requires a micro USB cable. No other dongles or adapters are needed. However, to support all development environments, including those with debuggers and dongles, a PC4 2x7 header has also been provided. 1.8V 1.8V 3.3V Vref PC4 Header K 1.8V Vdd Vref 8 11 Digilent JTAG-SMT2 Module musb Connector TDO TDI TMS TCK SOM_RESET_IN_N 2 TDI TMS TCK TDO UltraZed-EV SOM Slot TMS TCK 1.8V to 3.3V Voltage Translators TDI TMS TCK TDO FMC HPC Slot Figure 52 Carrier Card JTAG Topology Page 51

56 2.29 Fan Header JP14 The carrier card provides a dual position fan header for the SOM s cooling fan. The default configuration sources +5.0V to the SOM fan. If a 12V fan is used, FB10 and C215 need to be placed and FB11 removed. A ferrite bead and capacitor are used to minimize fan motor noise coupling to the carrier card s rails. The maximum current for the fan should not exceed 200mA Unused PL I/O Figure 59 JP14 Fan Header All unused PL I/O pins will be looped back on the UltraZed-EV Carrier Card PCB design using 0 Ohms resistors for testing.

57 3 Carrier Card Power The Carrier Card s power solution is designed to provide power to all of the interfaces/peripherals on the Carrier Card as well as provide power to the appropriate interfaces on the SOM. This section is broken up to define each subsection of power for clarity and ease of design. See the specific interface sections for more detail. 3.1 Power In connector J18 Due to the number and types of interfaces the UltraZed-EV SOM and Carrier are capable of supporting, the worst case power supply need is approximately ~102 Watts. This exceeds the standard Avnet 60 Watt power supply and therefore necessitated a new power solution to be used. The new power supply is capable of sourcing 12V at 10 Amps and has been designed for the Carrier Card and SOM combination. The standard 60W power supply pinout is not compatible with this Carrier Card and will not allow the board to power on. The six pin ATX-style connector remains, but the pinout has changed to prevent the 60W power supply from being able to power the system. Pins 2 & 5 are connected instead of pins 1 & 4. Removed L1 choke (on prior boards) due to new power supply chosen. Figure 61 New power jack pinout Page 57

58 3.2 Power Switch SW8 Power Switch SW8 is a CK 1101 slide switch with a contact rating of 6 Amps. While the contact rating is not sufficient for the potential 10 Amps of current, it has been kept in the design due to it s low cost and availability. In lieu of placing a higher current switch, and to control the in-rush current and voltage ramp on the power supply, a high power Infineon BSC030P03NS3 50 Amp P-Channel MOSFET has been designed in. New high power Infineon BSC030P03NS3 50 Amp P-MOSFET as high side switch. New low cost in-rush current and voltage ramp control using the P-MOSFET and Low Pass filter consisting of R204 and C174. By default, using the shipped Avnet 120W power supply, C174 is not required to be placed. Figure 62 Prior Low Pass Filter used on UZ-EG to control power-on ramp time Figure 63 NEW UZ-EV solution to control power-on ramp time, if needed Page 58

59 3.3 Power Input dedicated rails The below rails are listed as dedicated because they are independent of the power sequencing required for the SOM. These rails provide power once the board is turned on. +VIN 12V using a new pinout method to J18. U20, +3.3V Primary regulator powers the LDO regulators on the Infineon PMICs.

The pins are routed to a 0.1 SIP header for access to the SYSMON interface pins. Signals are routed differentially at 100 ohms. Termination resistors R206 and R207 are placed within 100 mils of J21. The signals are routed to within 10 mils across both pairs. Figure 65 J21, SYSMON Header Page 59

The below figure shows the available voltage monitor points. Figure 66 J19, J20 Voltage Monitor Headers 3.5 PMBus Interface J22 The UltraZed-EV CC and SOM s Power Management ICs can be accessed by attaching to the PMBus header, J22. This header can be used for monitoring and programming all PMBus voltage regulators on the Carrier Card and SOM. To attach to this interface the customer may use a generic I2C dongle or an Infinion USB005 dongle. NOTE: After the initial programming of all PMBus voltage regulators, the UltraZed-EV SOM can drive the PMBus in order to control/monitor the PMBus voltage regulators on the UltraZed-EV SOM as well as the Carrier Card for the purpose of power management and/or measurements. The PMBus signals are pulled up to 3.3V on the SOM. Page 60

These parts are programmed with the necessary files by the Avnet programming center and are orderable. All parts are PMBus accessible and therefore user configurable. All of the IRPS5401MTRPBF s used on the CC and SOM use a single programming file and the parts are orderable under a single part number. Please discuss with your Avnet account representative to get the part number. Each of the IRPS38063 PMICs have a unique part number assigned to them based on the programming file. Please discuss with your Avnet account representative to get the specific part number. Page 61

62 The UltraZed-EV SOM provides voltage sense feedbacks for each rail supplied by the carrier card. Please refer to Xilinx s ds925 for percent variation on the following power rails when designing the power system for a custom Carrier Card. 3.7 Power Control The UltraZed-EV SOM provides a signal named SOM_PG_OUT signal (3.3V level) that is used by the Carrier Card for PMIC power sequencing. The Carrier Card voltage regulators are not turned ON until the SOM_PG_OUT signal is asserted. SOM/CC Net Name: JX1 Pin #: SOM_PG_OUT D47 Table 32: SOM_PG_OUT input to Carrier Card NOTE: In normal operation, the SOM_PG_OUT signal controls the CC s PMIC enable pins. For this reason a SOM must be placed for the carrier to power up in normal operation. In test mode, the CC board can be powered up by modifying the circuits as described below. To power up the board without a SOM, the user can populate JP15 and then place a jumper on the pins. In addition to placing the jumper, the user will have to populate the not-fitted components on each regulator output to provide feedback to the PMICs. See each PMIC section. The CC has a 49.9K weak pull up which turns on the carrier card s PMICs. While it is recommended a SOM not be placed when this modification is made, the resistor value is high enough to allow the SOM to maintain control of the CC s SOM_PG_OUT signal. Figure 69 JP15 PMIC ON test header 3.8 Infineon IRPS38063MTRPBF PMIC U18, 0x1B U18 provides a 1.8V high current rail (20 amps max) for the Carrier Card s main 1.8V power supply. The Infineon IRPS38063MTRPBF PMIC was chosen due to it s small size, high efficiency, high power and PMBus programmable features. A remote feedback sense line is used at the highest current interface on the board. This technique increases the voltage accuracy over high load conditions.

The Infineon IRPS38063MTRPBF PMIC was chosen due to it s small size, high efficiency, high power and PMBus programmable features. A remote feedback sense line is used at the highest current interface on the board. This technique increases the voltage accuracy over high load conditions. The part has been Avnet programmed for this application. Note: the feedback scale is set to 0.5 due to the output voltage being greater than 2.5V. This is per Infineon s recommendations. The IRPS38063 PMIC has been programmed as follows: Vout_command: 3.30V Vout_max: 3.500V Iout fault: 33 amps max Frequency: 607 KHz Transition rate: 0.125mV/us Point of load sense via R288 Feedback Vout scale: 0.5 Turn off outputs if PMIC input voltage is less than 9.0V Turn on outputs if PMIC input voltage is equal or greater than 11.0V R217 provided for Bode plot measurements if needed.

The part has been factory programmed with 3 selectable output profiles. One profile is used for the carrier card, while the remaining two are used for the SOM.

The Maxim Part MAX8902BATA+T creates this rail. Features include: Vout is high precision, (<1.5% Vout) & low noise (16uVRMS) 500mA source in normal operation 700mA source in short mode Auto thermal shutdown and protect POK output 2mm X 2mm package Page 76

Figure 82 U1, +3.3V Display Port regulator 3.13 PS VBATT LR44 Battery JP13 & BTH-1 The Carrier Card provides two methods of maintaining the SOM s Zynq device volatile AES decryptor keys when the carrier is turned off. A 1.5V LR44 battery or a customer connection through JP13. Either connection provides power to the SOM s +PS_VBATT signal via the JX3 pin C21 connector. When the carrier card is turned on, neither method is required as +VCCO_1V8 is diode OR d with +PS_VBATT signal. The +PS_VBATT pin is pulled up via +VCCO_1V8 & D43 when the board is powered on, no battery or external power source needed to maintain decryptor keys. Place a LR44 battery to maintain the AES decryption keys on the SOM when board is power off. Diode D43 and D45 provide back source isolation for +VCCO_1V8 & LR44 battery. In lieu of placing a LR44 battery, the user may decide to use an external power supply or battery connected via JP13. In doing so, the input voltage on JP13 MUST NOT EXCEED 2.0 volts otherwise the SOM s FPGA may be damaged. Diode D44 and resistor R205 are placed to help prevent this, but this is by no means intended to encourage a voltage higher than 2.0V to be applied! Figure 83 +PS_VBATT circuit Page 77

The coin cell s positive terminal is placed into the opening of the sleeve facing UP. Figure 84 Battery & sleeve orientation prior to insertion Page 78

80 3.15 Power Supply Sequencing and Power Modes Sequencing for the power supplies follows the datasheet recommendations for the Zynq UltraScale+ device. The power configuration programmed into the International Rectifier IRPS5401MTRPBF and IR3806MTRPBF devices controls the power supply sequencing. An end-user may utilize the PMBUS on the carrier-card or utilize the Zynq UltraScale+ MPSoC interface to the PMBUS to power down individual rails to implement the different power modes supported by the MPSoC. Sequencing is needed for board power up, as well as entering and exiting different power modes. There are 3 power domains, PS LP (Processing Subsystem Low Power), PS FP (Processing Subsystem Full Power) and PL (Programmable Logic Power). The PS LP domain shall come up first followed by the PS FP and PL power domains. PS LP Power Domain Sequence: DS925 (V1.8) Recommended: VCC_PSINTLP VCC_PSAUX / VCC_PSADC / VCC_PSPLL VCCO_PSIO UltraZed-EV SOM Implementation: VCC_PSINTLP VCCO_PSIO / VCC_PSPLL VCCO_PSIO_501 (From Carrier Card) PS FP Power Domain Sequence: DS925 (V1.8) Recommended: VCC_PSINTFP / VCC_PSINTFP_DDR PS_MGTRAVCC / VCC_PSDDR_PLL PS_MGTRAVTT / VCCO_PSDDR UltraZed-EV SOM Implementation: VCC_PSINTFP MGTRAVCC (From Carrier Card) / VCC_PSDDR_PLL (Generated from +3.3V on SOM) MGTAVTT (From Carrier Card) / VCCO_PSDDR4_504 PL Power Domain Sequence: DS925 (V1.8) Recommended: VCCINT VCCINT_IO / VCCBRAM / VCCINT_VCU VCCAUX / VCCAUX_IO VCCO_HD_47 / VCCO_HD_48 / VCCO_HP_64 / VCCO_HP_65 / VCCO_HP_66 / MGTAVCC / MGTAVTT / MGTVCCAUX UltraZed-EV SOM Implementation: VCCINT VCU_INT VCCAUX VCCO_HD_47 (From Carrier Card) / VCCO_HD_48 (From Carrier Card) / VCCO_HP_64 (From Carrier Card) / VCCO_HP_65 (From Carrier Card) / VCCO_HP_66 / MGTAVCC (From Carrier Card) / MGTAVTT (From Carrier Card) / MGTVCCAUX (From Carrier Card) Entering / Exiting Power Domains: To enter power down modes, the reverse order of start-up should be followed (last supply to come up should be the first to be shut down, etc.). The PL and PS FP domains can be powered down independently and either can be powered down before or after the other. When shutting down power to a domain however, sequencing must be followed in relation to the specific power domain group. Upon repowering these domains, proper sequencing should again be followed. The following diagrams are indicative of the pre-programmed power-on and power-off sequences that exist on the UltraZed-EV SOM and the UltraZed-EV Carrier Card. Page 80
