assumes that the LVPECL clock driver’s output impedance is 50
R1 is used to DC-bias the LVPECL
outputs prior to AC-coupling. Its value could be ranged from 140
to 240depending on clock driver
vendor’s requirement. R2 is used together with the SerDes reference clock receiver’s 50-
termination
resistor to attenuate the LVPECL output’s differential peak level such that it meets the MPC8315E 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
Please
consult clock driver chip manufacturer to verify whether this connection scheme is compatible with a
particular clock driver chip.
Figure 45. AC-Coupled Differential Connection with LVPECL Clock Driver (Reference Only)
This figure 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 MPC8315E SerDes reference clock
input’s DC requirement.
