Introduction

EPCIE4XRDCA01-G2 is External PCI Express x4 (with Gen 2 Redriver) Cable Adapter Card, it requires no additional software or drivers to operate.

Designed to overcome the limited PCIe connectivity of most desktop computers, the EPCIE4XRDCA01-G2 can be quickly and easily set up for external expansion.

It provides programmable equalization, amplification, and de-emphasis by using 8 select bits, to optimize performance over a variety of physical mediums by reducing Inter-symbol interface. The integrated equalization circuitry provides flexibility with signal integrity of the PCI Express signal before the Redriver, whereas the integrated de-emphasis circuitry provides flexibility with signal integrity of the PCI Express signal after the Redriver.
