Chapter 1 Introduction

The Terasic PCIe x4 Cable Adapter (PCA3) is used to connect a PCIe upstream slot with downstream target board via PCIe x4 cable, supporting PCIe x4 & x1 lanes. The PCA3 can provide programmable equalization, amplification, and de-emphasis for PCIe transceiver signal by using 8 select bits. It is also available to optimize performance over a variety of physical mediums by reducing Inter-symbol interference.

Features

Figure 1-1 shows a photograph of the PCA3 card.
