SerDes Transmitter and Receiver Reference Circuits
Figure 47 shows the reference circuits for SerDes data lane’s transmitter and receiver.
Figure 47. 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, Serial Rapid IO, or SGMII) in this document based on the application usage:
Note that external an AC coupling capacitor is required for the above three serial transmission protocols
with the capacitor value defined in the specification of each protocol section.
16 PCI Express
This section describes the DC and AC electrical specifications for the PCI Express bus of the MPC8548E.
