SerDes Transmitter and Receiver Reference Circuits
Figure 49 shows the reference circuits for SerDes data lane’s transmitter and receiver.
Figure 49. SerDes Transmitter and Receiver Reference Circuits
The DC and AC specification of SerDes data lanes are defined in each interface protocol section below
(PCI Express or Serial Rapid IO) in this document based on the application usage:”
Note that external AC Coupling capacitor is required for the above two serial transmission protocols with
the capacitor value defined in specification of each protocol section.
14 PCI Express
This section describes the DC and AC electrical specifications for the PCI Express bus of the MPC8641.
