LVPECL Clock Input Interface (2.5V)
The PCLK /nPCLK accepts LVPECL, LVDS and other differential
signals. The differential signal must meet the V_PP and V_CMR input
requirements. Figures 2A to 2C show interface examples 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.
