Introduction

EPCIE16XRDCA02A is External PCI Express (two SFF-8644 1x2) to PCIe x16 Gen 3 Active (Redriver with Linear Equalization) Cable Adapter Card, it requires no additional software or drivers to operate.

Designed to overcome the limited PCIe connectivity of most desktop computers, the EPCIE16XRDCA02A can be quickly and easily set up for external expansion.

It provides programmable equalization by using 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.
