• One PCIe x4 Cable Connector
• Low Profile PCI Form Factor
• Compliant with PCIe 1.0/2.0/3.0 mainboards
• Active (with Gen 2 Redriver) PCIe x4 Cable Adapter
• Up to 20Gbps 4-Lane PCIe^® 2.0 Serial ReDriver^TM
• I²C Configuration Controls (3.3V tolerant)
• Adjustable Receiver Equalization and Transmitter De-emphasis and Output Levels

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.

• 38pin iPass™ (0.8mm pitch) compatible I/O Connector
