AC Electrical Characteristics

All parameters are measured at f

≤ 1GHz, unless otherwise noted.

NOTE 1: Measured from the differential input crossing point to the differential output crossing point.

NOTE 2: Defined as skew between outputs at the same supply voltage and with equal load conditions.

Measured at the output differential cross points.

NOTE 3: Defined as skew between outputs on different devices operating at the same supply voltages and with equal load conditions.

Using the same type of inputs on each device, the outputs are measured at the differential cross points.

NOTE 4: The VCMR and VPP levels should be such that input low voltage never goes below VEE.

NOTE 5: This parameter is defined in accordance with JEDEC Standard 65.
