AC Electrical Characteristics

Table 5. AC Characteristics, VDD = 3.3V ± 5%, VDDO = 1.8V ±0.2V, TA = 0°C to 85°C

All parameters measured at fMAX unless noted otherwise.

The cycle to cycle jitter on the input will equal the jitter on the output. The part does not add jitter.

NOTE 1: Measured from either the differential input crossing point or VDD/2 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 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: This parameter is defined in accordance with JEDEC Standard 65.Parameter Measurement Information
