EVB-USB3340 USB Transceiver Evaluation Board User Manual

Revision 1.1 (12-14-10) 2 SMSC USB3340 EVB

USER MANUAL

1 Introduction

This user manual is for the USB3340 USB Transceiver Evaluation Board (EVB) for use with USB3340

products with the integrated USB switch.

The USB3340 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.

2 Overview

The USB3340 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 www.smsc.com or may be obtained from your

local FAE. The USB3340 EVB includes USB3340 packaged silicon and all external components

required for the USB transceiver function.

This manual describes PCB assembly PCB-7220AZ.

2.1 Supplying VBUS Voltage

In Host or OTG operation, the USB3340 EVB must provide 5 Volts on V

BUS

at the USB connector. The

USB3340 EVB includes a switch that can drive V

BUS

using the 5 Volt supply that comes from pin 28

of the T&MT connector.

The VBUS switch is controlled by the CPEN signal from the USB3340. The USB controller dictates

the state of CPEN by programming the ULPI register in the USB3340. 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 2.10 and Section 2.11 for more information on configuring the USB3340 EVB for

OTG and Host operation.

2.2 ULPI I/O Voltage

The USB3340 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 R18 is used to set VDDIO, the digital logic high voltage. To change the value of VDDIO,

calculate a new value for R18 (ohms) as follows.

R18 = (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 USB3340 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 USB3340 EVB must be the same as the

ULPI I/O voltage level that the link is using.

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.

2.4 REFCLK Frequency Selection

The USB3340 EVB offers a user selectable reference clock frequency. R25 - R30 are used to configure

the REFCLK[2:0] signals which will select the reference clock frequency desired on the USB3340 EVB.

Ensure that the frequency of the reference clock or reference crystal being used matches the desired

operation frequency configured based on Table 2.2 below. By default, the USB3340 EVB is configured

for 26MHz REFCLK operation.

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 USB3340. The USB3340 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. TP4 and TP5 connect to the Speaker Left and Speaker Right pins

respectively.

2.9 Speaker Left and Speaker Right signals

The Speaker Left and Speaker Right pins can accept audio signals ranging from 0V to 3.3V. If the

audio signal coming into the test points goes below 0V, biasing circuitry is required. Install R11, R14,

R15, and R16 with 10k resistors to add a DC bias to the audio signal. This will ensure the best signal

quality when routing through the USB3340.

2.10 Converting the EVB to an OTG System

“Out of the box”, the USB3340 EVB 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.

2. Remove R23. This is the R

VBUS

value required for a USB Device.

3. Install R10 (1.0K, 1W resistor). This is the R

VBUS

value required for a USB OTG Device.

Since the USB3340 is designed to accommodate up to 30V on VBUS, R10 is rated at 1W to

accommodate this entire voltage range. Refer to the USB3340 datasheet for more information on sizing

this resistor.

2.11 Converting the EVB to a Host System

“Out of the box”, the USB3340 EVB 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 C24 (120uF capacitor). This increases the value of C

VBUS

to be USB 2.0 Host compliant.

2.12 Converting the EVB to Support ULPI Clock Input Mode

“Out of the box”, the USB3340 EVB 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, R17, C22, C23

Refer to the USB3340 datasheet for more information on ULPI Clock Input Mode.

2.13 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 USB3340 EVB 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 2.3.

3 Getting Started

The block diagram in Figure 3.1 gives a simplified view of the USB3340 EVB. The USB3340 EVB is

ready for device operation. To modify the board for OTG or Host applications, refer to Section 2.10 or

Section 2.11, 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 USB3340 EVB.

The USB3340 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.

When the USB3340 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 USB3340

should be logic high = VDD18). If RESETB=0, the USB3340 will be in a low power state.

 The voltage at R2 (RBIAS) should be 0.8V DC. If this voltage is not present, the USB3340 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 USB3340.

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 USB3340 is fully tolerant to VBUS voltages up to 30V. An external resistor on the VBUS line

VBUS

) is required for the integrated overvoltage protection circuit in the USB3340. R

VBUS

is either

R10 or R23 on the USB3340 EVB. For peripheral and host applications, R

VBUS

is 10K (install R23,

remove R10). For OTG applications, R

VBUS

is 1K (install R10, remove R23).
