2 EVB-USB0 USB Transceiver Evaluation Board User Manual Introduction Overview This user manual is for the USB0 USB Transceiver Evaluation Board (EVB) for use with USB0 products with the integrated USB switch. The USB0 features a ULPI interface to support systems with USB Host, Device, or On-the-Go (OTG) capability. The integrated switch can be used to multiplex a Full Speed USB signal or audio signals over the HS USB DP/DM pins. The USB0 EVB is a Daughter Card designed to plug into a user's test system using a T&MT connector. The card attaches to a USB link layer to create a USB Host, Device, or On-the-Go (OTG) system. The board edge connector meets the UTMI+ Low Pin Interface (ULPI) Standard requirements for the T&MT connector. A link to the ULPI Working Group Page is available at or may be obtained from your local FAE. The USB0 EVB includes USB0 packaged silicon and all external components required for the USB transceiver function. This manual describes PCB assembly PCB-70AZ.. Supplying Voltage In Host or OTG operation, the USB0 EVB must provide Volts on V BUS at the USB connector. The USB0 EVB includes a switch that can drive V BUS using the Volt supply that comes from pin 8 of the T&MT connector. The switch is controlled by the CPEN signal from the USB0. The USB controller dictates the state of CPEN by programming the ULPI register in the USB0. The Volt switch is backdrive protected when in the off state. The switch does not provide protection from reverse currents when it is on. See Section.0 and Section. for more information on configuring the USB0 EVB for OTG and Host operation.. ULPI I/O Voltage The USB0 supports variable ULPI I/O voltage signaling. The ULPI I/O voltage is supplied in one of two ways. By default, the EVB is shipped with supplied by the on-board LDO. Resistor R8 is used to set, the digital logic high voltage. To change the value of, calculate a new value for R8 (ohms) as follows. R8 = (/.-) x must be in the range of.8 Volts -. Volts nominal. can also be supplied to the USB0 from the T&MT connector instead of using the LDO. To do this, the LDO (U0) must be removed. The voltage level that has been configured on the USB0 EVB must be the same as the ULPI I/O voltage level that the link is using. Revision. (--0) SMSC USB0 EVB

USB Connector A standard Mini-AB connector is provided to attach a USB cable or connector. Provision is made on the PCB to accept a Micro-AB connector. See the bill of materials in Section 6 for connector part numbers. Do not substitute a different part number for the Mini-AB receptacle or a short circuit of the USB signals may result at the micro-ab connector PCB footprint..6 Present Detection The USB controller must detect when a USB cable is attached in device mode or when the USB controller turns on in host or OTG mode. The USB connector signal is connected to the pin of the USB0. The USB0 includes all of the comparators required to detect and report the state of to the USB controller via the ULPI bus.

Install the Tektronix logic analyzer probe retention kit at J to probe these signals. Ordering information for the retention kit is provided in the bill of materials..8 Other Signal Test Points There are five other test points located on the board for easy access. TP connects to the V supply coming from the T&MT connector. TP connects to the.v VDD supply coming from the T&MT connector. TP connects to Ground. TP and TP connect to the Speaker Left and Speaker Right pins respectively..9 Speaker Left and Speaker Right signals The Speaker Left and Speaker Right pins can accept audio signals ranging from 0V to.v. If the audio signal coming into the test points goes below 0V, biasing circuitry is required. Install R, R, R, and R6 with 0k resistors to add a DC bias to the audio signal. This will ensure the best signal quality when routing through the USB0..0 Converting the EVB to an OTG System Out of the box, the USB0 EVB is delivered as a USB Device system. To convert it to be a USB OTG development board, the following modifications must be made:. Install R (zero ohm resistor). This connects the V switch to the signal.. Remove R. This is the R value required for a USB Device.. Install R0 (.0K, W resistor). This is the R value required for a USB OTG Device. Since the USB0 is designed to accommodate up to 0V on, R0 is rated at W to accommodate this entire voltage range. Refer to the USB0 datasheet for more information on sizing this resistor.. Converting the EVB to a Host System Out of the box, the USB0 EVB is delivered as a USB Device System. To convert it to be a USB Host development board, the following modifications must be made:. Install R (zero ohm resistor). This connects the V switch to the signal.. Install C (0uF capacitor). This increases the value of C to be USB.0 Host compliant.. Converting the EVB to Support ULPI Clock Input Mode Out of the box, the USB0 EVB uses a crystal (Y) as the clock reference, and is configured for ULPI Clock Output Mode where CLKOUT sources a 60MHz clock. To convert the EVB to support ULPI Clock Input Mode, the following changes must be made:. Install R (zero ohm resistor). This shorts CLKOUT to VDD8.. Install R (zero ohm resistor). This shorts REFCLK to the System Clock pin on the T&MT connector.. Confirm that R is not populated.. Remove the following components to remove the crystal circuit: Y, R7, C, C Refer to the USB0 datasheet for more information on ULPI Clock Input Mode. Revision. (--0) SMSC USB0 EVB

6 EVB-USB0 USB Transceiver Evaluation Board User Manual Getting Started The block diagram in Figure. gives a simplified view of the USB0 EVB. The USB0 EVB is ready for device operation. To modify the board for OTG or Host applications, refer to Section.0 or Section., respectively. It is required to provide +V to T&MT connector pin 8 and +.V on T&MT pins 8,6,7,69 to power the USB0 EVB. The USB0 EVB is built with a USB Mini-AB receptacle. Do not substitute a Mini-AB receptacle different from the one specified in the bill of materials, or a short circuit may occur on the USB signals at the Micro-AB connector PCB footprint.

Figure. Block Diagram of USB0 EVB When the USB0 EVB is powered on, check the following things to be certain the board is functioning normally: RESET should be de-asserted (logic low at the T&MT connector and RESETB at the USB0 should be logic high = VDD8). If RESETB=0, the USB0 will be in a low power state. The voltage at R (RBIAS) should be 0.8V DC. If this voltage is not present, the USB0 is in a low power state. There should be a digital 60 MHz square wave signal at T&MT connector pin 90. The amplitude should be approximately. This is the CLKOUT signal of the USB0. Revision. (--0) 6 SMSC USB0 EVB

7 EVB-USB0 USB Transceiver Evaluation Board User Manual The voltage at C should be approximately.v. This is the USB0 internal.v voltage regulator output. The voltage at C should be.8v. This is the.8v regulator output. Protecting from Non-Compliant Voltages The USB0 is fully tolerant to voltages up to 0V. An external resistor on the line (R ) is required for the integrated overvoltage protection circuit in the USB0. R is either R0 or R on the USB0 EVB. For peripheral and host applications, R is 0K (install R, remove R0). For OTG applications, R is K (install R0, remove R). SMSC USB0 EVB 7 Revision. (--0)
