High-Speed Serial Interfaces (HSSI)
Please consult with the 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)
Figure 46 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 MPC8640D SerDes reference clock
input’s DC requirement.

AC Requirements for SerDes Reference Clocks
The clock driver selected should provide a high quality reference clock with low phase noise and
cycle-to-cycle jitter. Phase noise less than 100 kHz can be tracked by the PLL and data recovery loops and
is less of a problem. Phase noise above 15 MHz is filtered by the PLL. The most problematic phase noise
