oscTOL Crystal Oscillator Tollerance

TBD

All parameters measured at 500MHz 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 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: Measured using CLK. For XTAL input, refer to Application Note.

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