Figure 64 shows the SerDes reference clock connection reference circuits for LVPECL type clock driver. Since LVPECL
driver’s DC levels (both common mode voltages and output swing) are incompatible with MPC8536E SerDes reference clock
input’s DC requirement, AC-coupling has to be used. Figure 64 assumes that the LVPECL clock driver’s output impedance is
50
Ω. R1 is used to DC-bias the LVPECL outputs prior to AC-coupling. Its value could be ranged from 140Ω to 240Ω depending
on clock driver vendor’s requirement. R2 is used together with the SerDes reference clock receiver’s 50-
Ω termination resistor
to attenuate the LVPECL output’s differential peak level such that it meets the MPC8536E SerDes reference clock’s differential
input amplitude requirement (between 200mV and 800mV differential peak). For example, if the LVPECL output’s differential
peak is 900mV and the desired SerDes reference clock input amplitude is selected as 600mV, the attenuation factor is 0.67,
which requires R2 = 25
Ω. Please consult clock driver chip manufacturer to verify whether this connection scheme is compatible
with a particular clock driver chip.

Figure 65 shows the SerDes reference clock connection reference circuits for a single-ended clock driver. It assumes the DC
levels of the clock driver are compatible with MPC8536E SerDes reference clock input’s DC requirement.
