Figure 51 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 MPC8572E 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 100KHz can be tracked by the PLL and data recovery loops and
is less of a problem. Phase noise above 15MHz is filtered by the PLL. The most problematic phase noise
occurs in the 1-15MHz range. The source impedance of the clock driver should be 50 ohms to match the
transmission line and reduce reflections which are a source of noise to the system.
Table 57 describes some AC parameters common to SGMII, PCI Express and Serial RapidIO protocols.
