Pericom PI3EQX7741ST EVB User Manual

Introduction
Pericom's PI3EQX7741ST is a low power high performance 5.0Gbps signal ReDriver designed for USB3.0 protocol.
The device provides programmable Equalization (EQ) and De-Emphasis (DE) to optimize performance over a variety
of physical mediums by reducing Inter-Symbol Interference (ISI)
The PI3EQX7741ST evaluation board (EVB) is designed to demonstrate the benefits, performance and key features
of PI3EQX7741ST. This user manual describes the usage of this EVB and it will be divided into following sections:

Overview
Figure 1 is the block diagram of Pericom PI3EQX7741ST Evaluation board (EVB) and Figures 2(a) and (b) is the
top and bottom view of EVB board. There is an USB3.0 Type-B Receptacle connector (JP6) which is used to
connect PC's USB3.0 port through a USB3.0 cable and the USB3.0 Type-A receptacle connector (JP7) is used to
connect USB3.0 HDD or Hub through a USB3.0 cable. The EQ and DE setting on SW1 are used to select the
equalization and de-emphasis level on PI3EQX7741ST. JP2 is used to enable receive detect function.
PI3EQX7741ST operation required +3.3V which was provided by the 3.3V LDO.
