Stresses greater than those listed under " Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only
and functional operation of the device at these or any other conditions above those indicated in the operating sections of this specification is not
implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.

specifies the maximum allowable DC level for the differential clock. i.e V
specifies the minimum Clock differential voltage required for switching. i.e DC voltage difference between V
specifies the Clock crossing point for the differential clock or the allowable common clock level for a single ended clock.
