Introduction of the PCA Card

PCA(PCIe Cable Adapter)，which is used to connect PCIe upstream slot with downstream target

board by a PCIe X4 cable , supports the PCIe X4 & X1 mode. PCA card 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.

Board Component

This chapter describes the specifications of the on board components.

3.1

PCIe

Edge

Connector

PCIe Edge Connector

This Edge connector is used to connect the PCA with PC motherboard PCIe slot, as show Figure

3-1 and Figure 3-2.

Figure 3-1 PCA Edge Connector

Figure 3-2 plug the PCA into motherboard PCIe slot

The pins are numbered as shown with side A on the top of the centerline on the solder side of the

board and side B on the bottom of the centerline on the component side of the board.

The PCIe interface pins PETpx, PETnx, PERpx, and PERnx are named with the following

convention: “PE” stands for PCIe high speed, “T” for Transmitter, “R” for Receiver, “p” for

positive (+), and “n” for negative (-).

Note that adjacent differential pairs are separated by two ground pins to manage the connector

crosstalk.

Table 3-1 gives the wiring information of the PCIe Edge connector.
