Introduction

EPCIE8XRDCA01 is External PCI Express x8 (with Gen1/2/3 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 EPCIE8XRDCA01 can be quickly and easily set up for external expansion.

It provides per channel programmable equalization, output swing, de-emphasis, and amplifier gain. The programmable settings can be applied easily via jumper. 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.
