SerDes Transmitter and Receiver Reference Circuits

This figure shows the reference circuits for SerDes data lane’s transmitter and receiver.

Figure 65. SerDes Transmitter and Receiver Reference Circuits

The DC and AC specification of SerDes data lanes are defined in each interface protocol section below in

this document based on the application usage:

•

Section 8, “Ethernet: Enhanced Three-Speed Ethernet (eTSEC)”

•

Section 15, “PCI Express”

Note that an external AC coupling capacitor is required for the above three serial transmission protocols

with the capacitor value defined in specification of each protocol section.
