High-Speed Serial Interfaces (HSSI)
clock driver chip manufacturer to verify whether this connection scheme is compatible with a particular
clock driver chip.
Figure 55. AC-Coupled Differential Connection with LVPECL Clock Driver (Reference Only)
Figure 56 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 device 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
