a. AC characteristics apply for parallel output termination of 50Ω to VTT.
b. 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 tPLH/HL and tSK(PP).
c. Violation of the 1.0 ns maximum input rise and fall time limit will affect the device propagation delay, device-to-device skew, reference input
pulse width, output duty cycle and maximum frequency specifications.
d. Output pulse skew is the absolute difference of the propagation delay times: | tpLH - tpHL |.
