Spread Spectrum Clock
SD1_REF_CLK/SD1_REF_CLK were designed to work with a spread spectrum clock (+0 to -0.5%
spreading at 30–33 kHz rate is allowed), assuming both ends have same reference clock. For better results,
a source without significant unintended modulation should be used.
SD2_REF_CLK/SD2_REF_CLK are not intended to be used with, and should not be clocked by, a spread
spectrum clock source.

SerDes Transmitter and Receiver Reference Circuits
Figure 55 shows the reference circuits for SerDes data lane’s transmitter and receiver.
Figure 55. SerDes Transmitter and Receiver Reference Circuits
The DC and AC specification of SerDes data lanes are defined in section below (PCI Express, or SGMII)
in this document based on the application usage:
Please note that external AC Coupling capacitor is required for the above serial transmission protocols
with the capacitor value defined in specification of each protocol section.
17 PCI Express
This section describes the DC and AC electrical specifications for the PCI Express bus of the MPC8544.
