PI3EQX501(I)
PI3EQX501(I) EVB Rev.A User Manual
By YT Tso, Anne Wu and Jessy Chen
Introduce:
PI3EQX501(I) is a 1-channel 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)
Quick Start — For Default Setting:
To start-up the PI3EQX501(I) EVB, complete the following steps:
For TX test,
1. Check the head pin status and follow Table 1
2. Connect the JP4 on EVB to PC’s USB3.0 port through a USB3.0 Type A to B cable.
3. Plug the USB3.0 device into EVB USB Type-A connector JP6 through USB3.0 cable
For RX test,
4. Check the head pin status and follow Table 1
5. Connect the JP10 on EVB to PC’s USB3.0 port through a USB3.0 Type A to B cable.
6. Plug the USB3.0 device into EVB USB Type-A connector JP11 through USB3.0 cable
