2.20.2.2
DC Level Requirement for SerDes Reference Clocks
The DC level requirement for the MPC8536E 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 400mV and 1600mV differential peak-peak (or
between 200mV and 800mV differential peak). In other words, each signal wire of the differential pair must have
a single-ended swing less than 800mV and greater than 200mV. This requirement is the same for both external
DC-coupled or AC-coupled connection.
—For external DC-coupled connection, as described in section 2.20.2.1, the maximum average current
requirements sets the requirement for average voltage (common mode voltage) to be between 100 mV and 400
mV. Figure 59 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 SnGND. Each signal wire of the differential inputs is allowed to swing below and
above the command mode voltage (SnGND). Figure 60 shows the SerDes reference clock input requirement for
AC-coupled connection scheme.
Single-ended Mode
— The reference clock can also be single-ended. The SDn_REF_CLK input amplitude (single-ended swing) must be
between 400mV and 800mV peak-peak (from Vmin to Vmax) with SDn_REF_CLK either left unconnected or
tied to ground.
— The SDn_REF_CLK input average voltage must be between 200 and 400 mV. Figure 61 shows the SerDes
reference clock input requirement for single-ended signaling mode.
— To meet the input amplitude requirement, the reference clock inputs might need to be DC or AC-coupled
externally. For the best noise performance, the reference of the clock could be DC or AC-coupled into the unused
phase (SDn_REF_CLK) through the same source impedance as the clock input (SDn_REF_CLK) in use.
