2.5V DIFFERENTIAL LVDS CLOCK BUFFER

Differential Clock Input Interface

The CLK/nCLK accepts LVPECL, LVDS and other differential

signals. Both differential signals must meet the VPP and VCMR input

requirements. Figures 2A to 2C show interface examples for the

CLK/nCLK 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.
