High-Speed Serial Interfaces (HSSI)
MPC8572E SerDes reference clock input’s DC requirement, AC-coupling has to be used. Figure 50
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 140
Ω 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 MPC8572E 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.
