High-Speed Serial Interfaces (HSSI)
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 MPC8640D SerDes reference clock
input’s DC requirement.
NOTE
Figure 43–Figure 46 are for conceptual reference only. Due to the
differences in the clock driver chip’s internal structure, output impedance,
and termination requirements among various clock driver chip
manufacturers, the clock circuit reference designs provided by clock driver
chip vendor may be different from what is shown above. They may 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 MPC8640D SerDes
reference clock receiver requirement provided in this document.
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 MPC8640D SerDes reference clock
input’s allowed range (100 to 400mV), AC-coupled connection scheme must be used. It assumes the
