      High-Speed Serial Interfaces (HSSI)
      LVPECL outputs can produce signal with too large amplitude and may need to be DC-biased at
      clock driver output first, then followed with series attenuation resistor to reduce the amplitude, in
      addition to AC-coupling.
      NOTE
      Figure 43 through Figure 46 below are for conceptual reference only. Due
      to the fact that clock driver chip's internal structure, output impedance and
      termination requirements are different between various clock driver chip
      manufacturers, it’s very possible that the clock circuit reference designs
      provided by clock driver chip vendor are different from what is shown
      below. They might also vary from one vendor to the other. Therefore,
      Freescale Semiconductor can neither provide the optimal clock driver
      reference circuits, nor guarantee the correctness of the following clock
      driver connection reference circuits. The system designer is recommended
      to contact the selected clock driver chip vendor for the optimal reference
      circuits with the MPC8548E SerDes reference clock receiver requirement
      provided in this document.
      Figure 43 shows the SerDes reference clock connection reference circuits for HCSL type clock driver. It
      assumes that the DC levels of the clock driver chip is compatible with MPC8548E SerDes reference clock
      input’s DC requirement.
      Figure 43. DC-Coupled Differential Connection with HCSL Clock Driver (Reference Only)
      Figure 44 shows the SerDes reference clock connection reference circuits for LVDS type clock driver.
      Since LVDS clock driver’s common mode voltage is higher than the MPC8548E SerDes reference clock
      input’s allowed range (100 to 400mV), AC-coupled connection scheme must be used. It assumes the
      LVDS output driver features 50-
      Ω termination resistor. It also assumes that the LVDS transmitter
      establishes its own common mode level without relying on the receiver or other external component.
