LVPECL Clock Input Interface
The PCLK /nPCLK accepts LVPECL, LVDS, SSTL and other
differential signals. The differential signal must meet the V
V
for the PCLK/nPCLK input driven by the most common driver types.

The input interfaces suggested here are examples only. If the driver
is from another vendor, use their termination recommendation.
Please consult with the vendor of the driver component to confirm the
driver termination requirements.
