a. AC characteristics are applicable over the entire ambient temperature and supply voltage range and are production tested. AC
characteristics apply for parallel output termination of 50

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 static phase offset t(鈭?.
c. Cycle鈥搕o鈥揷ycle and period jitter depends on output divider configuration.
d. See applications section for max I/O phase jitter versus frequency.
