6.4.1 PCIe Edge Connector

(Ask a Question)

PCIe is a point-to-point serial differential low-voltage interconnect supporting up to four channels. Each lane consists of two pairs of differential signals: transmit pair, receive pair, XCVR_x_TXy_P/N, and XCVR_x_RXy_P/N. Each signal has a 2.5 GHz embedded clock.

The following figure shows the connectivity between the transceiver interface and the PCIe edge connector.

Note: Between the fabric I/O and the host may require additional components to match 3.3 V levels.
