EVB-USB3330 USB Transceiver
Evaluation Board User Manual
EVB-USB3330 USB Transceiver Evaluation Board User Manual
Revision 1.1 (02-02-10) 2 SMSC EVB-USB3330
USER MANUAL
1 Introduction
This user manual is for the USB3330 USB Transceiver Evaluation Board (EVB) for use with USB3330
products.
The USB3330 features a ULPI interface to support systems with USB Host, Device, or On-the-Go
(OTG) capability. SMSC supplies a complete family of transceiver products to meet the needs of many
applications.
2 Overview
The EVB-USB3330 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-USB3330 includes USB3330 packaged silicon and all external components
required for the USB transceiver function.
This manual describes PCB assembly PCB-7164AZ.
2.1 Supplying VBUS Voltage
In Host or OTG operation, the EVB-USB3330 must provide 5 Volts on V
BUS at the USB connector. The
EVB-USB3330 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 pin on the T&MT connector. The presence of a zero
ohm resistor at R13 will route the 5V signal to the part and USB connectors. If R13 is empty then the
EVB will not supply 5V. The board will operate as a USB Peripheral. The 5 Volt switch is backdrive
protected when in the off state. See Section 2.7 and Section 2.8 for more information on configuring
the EVB-USB3330 for OTG and Host operation.
The zero ohm resistor on R24 can be removed to permanently leave the VBUS switch on.
2.2 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
2.3 REFCLK Frequency Selection
The EVB-USB3330 offers a user selectable reference clock frequency. R11, R14-R16 are used to
configure the REF[1:0] signals which will select the reference clock frequency desired on the EVB-
USB3330. 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 EVB-USB3330
