PCI Express
The other detailed AC requirements of the SerDes Reference Clocks is defined by each interface protocol
based on application usage. Refer to the following sections for detailed information:
15.2.4.1
Spread Spectrum Clock
SD_REF_CLK/SD_REF_CLK are not intended to be used with, and should not be clocked by, a spread
spectrum clock source.
15.3
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 SGMII) 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.
16 PCI Express
This section describes the DC and AC electrical specifications for the PCI Express bus of the MPC8315E.
16.1
DC Requirements for PCI Express SD_REF_CLK and
SD_REF_CLK
