High-Speed Serial Interfaces (HSSI)
— If the device driving the SDn_REF_CLK and SDn_REF_CLK inputs cannot drive 50
Ω to
SGND_SRDSn (xcorevss) DC, or it exceeds the maximum input current limitations, then it
must be AC-coupled off-chip.
The input amplitude requirement
— This requirement is described in detail in the following sections.

DC Level Requirement for SerDes Reference Clocks
The DC level requirement for the MPC8533E SerDes reference clock inputs is different depending on the
signaling mode used to connect the clock driver chip and SerDes reference clock inputs as described
below.
Differential Mode
— The input amplitude of the differential clock must be between 400 and 1600 mV differential
peak-peak (or between 200 and 800 mV differential peak). In other words, each signal wire of
the differential pair must have a single-ended swing less than 800 mV and greater than 200 mV.
This requirement is the same for both external DC-coupled or AC-coupled connection.
— For external DC-coupled connection, as described in Section 16.2.1, “SerDes Reference
Clock Receiver Characteristics,” the maximum average current requirements sets the
requirement for average voltage (common mode voltage) to be between 100 and 400 mV.
Figure 42 shows the SerDes reference clock input requirement for DC-coupled connection
scheme.
— For external AC-coupled connection, there is no common mode voltage requirement for the
clock driver. Since the external AC-coupling capacitor blocks the DC level, the clock driver
and the SerDes reference clock receiver operate in different command mode voltages. The
SerDes reference clock receiver in this connection scheme has its common mode voltage set to
SGND_SRDSn. Each signal wire of the differential inputs is allowed to swing below and above
the command mode voltage (SGND_SRDSn). Figure 43 shows the SerDes reference clock
input requirement for AC-coupled connection scheme.
