High-Speed Serial Interfaces (HSSI)
NOTE
fact that clock driver chip's internal structure, output impedance, and
termination requirements are different between various clock driver chip
manufacturers, it is very possible that the clock circuit reference designs
provided by the 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 device SerDes reference clock receiver requirement
provided in this document.
Figure 53 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 device SerDes reference clock
input’s DC requirement.
Figure 53. DC-Coupled Differential Connection with HCSL Clock Driver (Reference Only)
Figure 54 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 device SerDes reference clock input’s
allowed range (100 to 400 mV), AC-coupled connection scheme must be used. It assumes the LVDS
