ICS8545BG REV. D OCTOBER 28, 2008

AC Electrical Characteristics

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

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