USER MANUAL
1 Introduction
The USB3740 EVB demonstrates the capabilities of the USB3740. The board consists of the upstream
and downstream ports, manual switches to control the OE_N and S pins, and a second USB3740 that
can be evaluated with SMA connectors instead of USB (SMA connectors not installed).
2 Hardware
2.1 USB Ports
The USB ports are mounted on the edges of the USB3740 EVB. The downstream ports use the
standard USB Type A receptacle. The label for the port is located next to the receptacle. The upstream
port can be a standard USB Type B, mini-B or micro-B receptacle, the default connector is a USB mini-
B connector.
2.2 Test Points and Resistors
The USB3740 EVB provides access to the OE_N, S, VDD and GND pins. TP2 connects to GND, TP1
connects to the VDD pin. R1 (On the back of the PCB) connects the upstream VBUS to the VDD of
the USB3740. R2 and R3 connect the upstream VBUS to the VBUS pins of the dowstream ports. SW1
and SW2 control the operation of the switch. SW1 controls the Output Enable (OE_N) pin. To enable
the switch, OE_N should be set to 0. SW2 selects which downstream port is connected to the upstream
port.

2.3 SMA Evaluation (Not Installed)
The USB3740 EVB also contains a section to evaluate the USB3740 without the standard USB
connectors. Because the switch can be used in many different applications, a second USB3740 is
placed on the board with the pins routed out to right angle SMA connectors. The connectors are not
populated by default. R5 is used to supply VDD to the second USB3740.
