Notes:

AC characteristics apply for parallel output termination of 50

Ω to V

TT. Parameters are guaranteed by characterization and are not 100% tested.

VCMR (AC) is the crosspoint of the differential input signal. Normal AC operation is obtained when the crosspoint is within the VCMR range and the input swing

lies within the VPP (AC) specification. Violation of VCMR or VPP impacts static phase offset t(φ).
