5 3 General Description The PC720 is a high-performance, half-size PCI Express card with advanced Digital Signal Processing (DSP) capabilities and multiple I/O options. The PC720 offers various direct onboard interface options (2x FMC sites) that are closely coupled to the Kintex-7 and 1GB of DDR3 SDRAM. It is an excellent choice for high-performance applications that require large band signals digitization or generation through the use of accelerated frequency-domain algorithms or video applications that are bandwidth hungry. The PCIe interface can support up to eight high-speed GTX signals, with four primary signals and an additional four signals if they are not required for the secondary or primary FMC interface. The primary method of communication between the FPGA FMCs is by LVDS. The primary FMC is full High Pin-count (HPC) compliant for the LVDS signals, and supports up to four high speed lanes. The secondary FMC is a Low pin-count FMC site with optional support for four high speed lanes. clocks microsd slot DDR3 SDRAM 512MB (256Mbx16) DDR3 SDRAM 512MB (256Mbx16) Kintex-7 XC7K160T XC7K325T XC7K410T FFG676 XC2C256 CPLD CP132 JTAG 256 Mb Serial flash s25fl256p 33 LVDS or 66 SE 4x GTX 4x GTX PCIe Switch PCIe Switch 4x GTX 80 LVDS or 160 SE 4x GTX CPLD JTAG 8x GTX JTAG PCIe Interface PCIe Gen2 x8 or x4 PCIe FMC (LPC) VITA 57.1 FMCxxx (Secondary) 2 LVDS or 4 SE FMC (HPC) VITA 57.1 FMCxxx (Primary) Figure 1: PC720 Block Diagram UM030 page 5 of 37

6 4 Design 4.1 Physical specifications Board Dimensions The PC720 card complies with the PCIe Electromechanical Specifications standard except for the board width which is 205 mm instead of 167 mm. In addition, the restricted component height on the secondary side will not be compliant if a secondary FMC is used. In that case, the adjacent slot on the secondary side cannot be used, as it will be occupied by the secondary FMC. Excluding the PCIe interface, the PC720 is 205mm x mm. With only an FMC mounted on the Primary side, the PC720 consumes only one slot in a system. Please refer to Appendix D Final PC720 Assembly for more details. NOTE: In some cases, the cooling fans can conflict with the adjacent slot as well. Contact sales for detailed information Front Panel Both the Primary and Secondary FMCs have front panel I/Os available on the PCI Express card. Only the secondary FMC has its I/Os on the adjacent slot. 4.2 I2C Bus Architecture The PC720 contains an I2C bus that interfaces to the FPGA, all FMCs, the on-board CPLD, and the PCIe SMBus on the PCIe connector. A NXP PCA9548A I2C mux is used to switch the clock and data lines between all the interfaces. With the I2C bus architecture, the bus master is considered the FPGA. From that point, it is possible to gain access to the PC720 CPLD, which controls the PCIe switch, the VADJ regulator that goes to the Secondary FMC, and the four most significant bits of the LA pins of the same Secondary FMC connector. The hardware selectable address lines [A2:A0] of the PCA9548A are all grounded. Therefore, the PCA9548A slave address is found in Figure 2. Table 2 shows the I2C channels connected to PCA9548A R/W Figure 2: PCA9548A Slave address for PC720.

Four GTX signals from bank 115 connect to PCIe interface. The other four GTX signals from bank 116 connect to the PCIe interface, the Primary FMC, or the Secondary FMC. The signals from bank 116 can be changed either manually using the DIP switches (SW1 and SW2) or using PCIe_CTL signals from the CPLD. SW 1 and 2 are off by default, which means CPLD controls the switches. Please refer to Figure 10 for the switch location. The default CPLD design does not actively drive these signals, which means they are pulled high. With the default CPLD code, the SW1 and SW2 function will be as described in Table 3. Note that PC720 r1.0 does not have a SW2. The GTX signals connect to either the PCIe interface or the Secondary FMC.

Differential routing is applied with matched delay on all pairs. The FMC site provides flexibility for adding analog and/or digital I/O via customer developed, third party, or Abaco Systems FMC boards.

Furthermore, the FPGA receives clock signals that originate from the two FMCs and the PCIe connector. The clock signals between the Secondary FMC and the FPGA are restricted in voltage so as not to damage the FPGA pins. The voltage levels are limited to 1.8V LVCMOS or LVDS signalling levels.

The PC-FMC-ADAPTER card can also use fans for additional airflow FPGA Configuration CPLD JTAG Chain The JTAG chain on the PC720 is available for configuration and debugging purposes. The PC720 CPLD is used as JTAG control logic between the PCIe connector, the JTAG connector (Molex), two FMC connectors, and FPGA. CPLD detects the signals of each connector and determines the correct JTAG chain. Xilinx Platform USB-II is required to configure the FPGA. How to program the FPGA? - Connect a Xilinx Platform USB-II to the host computer. - Connect a Xilinx JTAG RIBBON cable between JTAG RIBBON connector on PC720 and Xilinx Platform USB-II. - Open impact and initialize the JTAG chain.

It is possible to program the flash directly from the JTAG chain using Xilinx tool impact. Please refer to Appendix C FLASH programming using impact for details on configuring the SPI flash using this tool. Additionally, Abaco Systems offers a reference design that allows configuration of the flash over the PCI express connector using the Abaco Systems software tools. Refer to the software getting started guide for information how to configure the flash over the PCI Express bus. UM030 page 20 of 37

21 Please note that the FPGA will configure itself using master SPI mode. The ISE bitstream generation settings target a master SPI clock of 3 MHz by default. The PC720 supports a maximum master SPI clock of 16 MHz when the SPI falling edge mode is also selected. For the fastest possible power on configuration time, the bitstream compression should also be enabled. NOTE: power up configuration can take between two and eight seconds depending on your FPGA image size and the configuration clock frequency. In some cases this is not fast enough to ensure proper detection of the FPGA by the host computer. You can: - try to slow down the BIOS - restart / reset the computer after the FPGA has loaded from flash CPLD The CPLD uses its own JTAG chain, by way of the press-fit interface, in order to be programmed. The default factory program provides the CPLD with several functions: a buffer and multiplexer for the JTAG chain to the PCIe interface and FMC interfaces; control of the VADJ regulator for the Secondary FMC; control of the PCIe switch for the high-speed signals from the FPGA Secondary Connector; and an interface to the LA32_P/N and LA33_P/N signals of the Secondary FMC. Within the CPLD, an I2C core is used to control the enable pin of the VADJ regulator and adjust its values, as well as to control the PCIe switch. With this capability, the FPGA can then control these devices by way of the CPLD. The I2C is also used to read and write to the LA32 and LA33 bits of the Secondary FMC. How to program the CPLD? - This should not be done without contacting Abaco Systems. - Connect a Xilinx Platform USB-II to the host computer. - Connect a Xilinx JTAG cable between JTAG header and Xilinx Platform USB-II. - Open impact and initialize the JTAG chain PCIe Interface The Kintex-7 devices can support the PCIe x1, x2, and x4 Gen2 lane widths on all the devices. Furthermore, FPGA devices that are not -1 parts can support x8 Gen 2. From the FPGA, the high-speed (DP) signals will start at DP0 for the x1 up to DP3 for the x4 lanes. For the x8 UM030 page 21 of 37

22 capability, the high-speed signals on the Secondary connector are accessed using the PCIe switch (SW1). The signals from the PCIe switch can be changed either manually using the DIP switch or using PCIe_CTL signals from the CPLD. SW1 is off by default, which means PCIe_CTL is pulled-up high and all 8 lanes connect to the PCIe card edge connector.

Because the adapter card restricts fan height for the Primary and Secondary FMCs, the fan height is set to 3 mm. Two fan locations are present under both FMCs to allow for air flow and/or an additional fan to be placed. Each fan uses about 37 ma (.10W) to create 0.57 CFM. UM030 page 23 of 37

24 A 30mm x 30mm fan is used for the FPGA. The 12-V fan uses approximately 100 ma (1.2W) to create 5.0 CFM. The fans for the FPGA and the Primary FMC are mounted to the PC720. The fan to the Secondary FMC is mounted to the PC-FMC-ADAPTER. Abaco Systems s warranty does not cover boards on which the maximum allowed temperature has been exceeded Heat Sink cooling (Enhanced FPGA Cooling Option) For applications where the on-board FPGA requires additional cooling, a heat sink is available. To support the heat sink, the 30mm x 30mm FAN must be moved to the bottom side of the PC720. It is important to note that making this change to the PC720 assembly will cause a violation of the PCIe specifications with regard to the bottom side maximum component height. The PCIe specification allows components with a maximum height of 2.67mm, the actual height of the FAN will be approximately 7-8mm (see Appendix D Final PC720 Assembly for details). Careful examination of clearances will be required if another card must be installed in the host system next to the PC720. The heat sink option needs to be specified at the time of order. 6 Safety This module presents no hazard to the user. 7 EMC This module is designed to operate within an enclosed host system built to provide EMC shielding. Operation within the EU EMC guidelines is not guaranteed unless it is installed within an adequate host system. This module is protected from damage by fast voltage transients originating from outside the host system which may be introduced through the system. 8 Warranty Hardware Software/Firmware Basic Warranty (included) 1 Year from Date of Shipment 90 Days from Date of Shipment Extended Warranty (optional) 2 Years from Date of Shipment Year from Date of Shipment UM030 page 24 of 37

27 Appendix C FLASH programming using impact NOTE: flash programming using impact is not guaranteed to work since the CPLD sits between the FPGA and the configuration flash (refer to Figure 1). This setup does not follow the recommended configuration schemes provided by Xilinx. impact loads an enhanced programming file into the FPGA that allows access to the flash, and the user will not have any control over the timing of this enhanced bit file. A fault condition might appear during the programming because the CPLD has an effect on the timing of the SPI interface to the flash device. Therefore Abaco Systems recommends to use the PC720 Board Support Package to program a.hex file into the flash. Choose the SPI flash and select configure single FPGA Press the green arrow.
