SMSC EVB-USB3343 SMSC CONFIDENTIAL - USER MANUAL Revision 1.0 (08-18-10) EVB-USB3343 USB Transceiver Evaluation Board User Manual 1 Introduction This user manual is for the USB3343 USB Transceiver Evaluation Board (EVB) for use with the USB3343 products with support for variable I/O voltage levels and 26MHz crystal operation. The USB3343 features a ULPI interface to support systems with USB Host, Device, or On-the-Go (OTG) capability. 2 Overview The EVB-USB3343 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 www.smsc.com or may be obtained from your local FAE. The EVB-USB3343 includes USB3343 packaged silicon and all external components required for the USB transceiver function. This manual describes PCB assembly PCB-7202AZ. 2.1 Supplying VBUS Voltage In Host or OTG operation, the EVB-USB3343 must provide 5 Volts on VBUS at the USB connector. The EVB-USB3343 includes a switch that can drive VBUS using the 5 Volt supply that comes from pin 28 of the T&MT connector. The VBUS switch is controlled by the DRVVBUS signal driven from the Link (T&MT connector). The 5 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 2.9 and Section 2.10 for more information on configuring the EVB-USB3343 for OTG and Host operation. 2.2 ULPI I/O Voltage The USB3343 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 VDDIO supplied by the on-board LDO. Resistor R11 is used to set VDDIO, the digital logic high voltage. To change the value of VDDIO, calculate a new value for R27 (ohms) as follows. R11 = (VDDIO/1.225-1) x 169000 VDDIO must be in the range of 1.8 Volts - 3.3 Volts nominal. VDDIO can also be supplied to the USB3343 from the T&MT connector instead of using the LDO. To do this, the LDO (U10) must be removed. The VDDIO voltage level that has been configured on the EVB-USB3343 must be the same as the ULPI I/O voltage level that the link is using. Revision 1.0 (08-18-10) 2 SMSC CONFIDENTIAL - USER MANUAL SMSC EVB-USB3343 EVB-USB3343 USB Transceiver Evaluation Board User Manual 2.3 Edge Connector for Digital I/O The T&MT edge connector is compliant to the ULPI specification. Part numbers and manufacturers for this connector and it’s mate are given in Table 2.1. Table 2.1 Edge Connector on the EVB-USB3343 2.4 PART NUMBER DESCRIPTION MANUFACTURER 2-557101-5 100 pin edge connector on EVB-USB3343 AMP 2-557-101-5 Mating connector to the EVB-USB3343 AMP 1-1734037-0 Alternate 100 pin edge connector for EVB-USB3343 TYCO 1-1734099-0 Alternate mating connector to the EVB-USB3343 TYCO REFCLK Frequency Selection The EVB-USB3343 is by default configured for operation with a 26MHz crystal (Y1). The EVB also accomodates the use of a 26MHz oscillator (X1). To use a 26MHz oscillator, X1, U6, and R4 must be populated, and Y1, R30, and C22 must be removed. 2.5 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. 2.6 VBUS Present Detection The USB controller must detect VBUS when a USB cable is attached in device mode or when the USB controller turns on VBUS in host or OTG mode. The USB connector VBUS signal is connected to the VBUS pin of the USB3343. The USB3343 includes all of the comparators required to detect VBUS and report the state of VBUS to the USB controller via the ULPI bus. 2.7 ULPI Signal Test Points Probe points at location J2, provide access to all ULPI signals. Install the Tektronix logic analyzer probe retention kit at J2 to probe these signals. Ordering information for the retention kit is provided in the bill of materials. 2.8 Other Signal Test Points There are five other test points located on the board for easy access. TP1 connects to the 5V supply coming from the T&MT connector. TP2 connects to the 3.3V VDD supply coming from the T&MT connector. TP3 connects to Ground. 2.9 Converting the EVB to an OTG System “Out of the box”, the EVB-USB3343 is delivered as a USB Device system. To convert it to be a USB OTG development board, the following modifications must be made: 1. Install R13 (zero ohm resistor). This connects the VBUS 5V switch to the VBUS signal. SMSC EVB-USB3343 3 SMSC CONFIDENTIAL - USER MANUAL Revision 1.0 (08-18-10) EVB-USB3343 USB Transceiver Evaluation Board User Manual 2. Remove R23. This is the RVBUS value required for a USB Device. 3. Install R10 (1.0K, 1W resistor). This is the RVBUS value required for a USB OTG Device. Since the USB3343 is designed to accommodate up to 30V on VBUS, R10 is rated at 1W to accommodate this entire voltage range. Refer to the USB3343 datasheet for more information on sizing this resistor. 2.10 Converting the EVB to a Host System “Out of the box”, the EVB-USB3343 is delivered as a USB Device System. To convert it to be a USB Host development board, the following modifications must be made: 1. Install R13 (zero ohm resistor). This connects the VBUS 5V switch to the VBUS signal. 2. Install C20 (150uF capacitor). This increases the value of CVBUS to be USB 2.0 Host compliant. 2.11 Converting the EVB to Support ULPI Clock Input Mode “Out of the box”, the EVB-USB3343 uses a crystal (Y1) 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: 1. Install R12 (zero ohm resistor). This shorts CLKOUT to VDD18. 2. Install R3 (zero ohm resistor). This shorts REFCLK to the System Clock pin on the T&MT connector. 3. Confirm that R4 is not populated. 4. Remove the following components to remove the crystal circuit: Y1, R30, C22, C23 Refer to the USB3343 datasheet for more information on ULPI Clock Input Mode. 2.12 T&MT Pin Description The T&MT signal names, pin number and function are described in Table 43 and Table 44 of the ULPI Specification rev 1.1. The EVB-USB3343 fully implements a ULPI compliant interface to the T&MT connector, including support for ULPI Clock Input Mode. This EVB supports a 1.8-3.3V ULPI I/O voltages. All signals are described in Table 2.2.

The EVB-USB3343 is ready for device operation. To modify the board for OTG or Host applications, refer to Section 2.9 or Section 2.10, respectively. It is required to provide +5V to T&MT connector pin 28 and +3.3V on T&MT pins 8,16,57,69 to power the EVB-USB3343. The EVB-USB3343 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.

If RESETB=0, the USB3343 will be in a low power state. Revision 1.0 (08-18-10) 6 SMSC CONFIDENTIAL - USER MANUAL SMSC EVB-USB3343 EVB-USB3343 USB Transceiver Evaluation Board User Manual The voltage at R2 (RBIAS) should be 0.8V DC. If this voltage is not present, the USB3343 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 VDDIO. This is the CLKOUT signal of the USB3343. The voltage at C3 should be approximately 3.3V. This is the USB3343 internal 3.3V voltage regulator output. The voltage at C4 should be 1.8V. This is the 1.8V regulator output. 4 Protecting VBUS from Non-Compliant VBUS Voltages The USB3343 is fully tolerant to VBUS voltages up to 30V. An external resistor on the VBUS line (RVBUS) is required for the integrated overvoltage protection circuit in the USB3343. RVBUS is either R10 or R23 on the EVB-USB3343. For peripheral and host applications, RVBUS is 10K (install R23, remove R10). For OTG applications, RVBUS is 1K (install R10, remove R23).
