AC Electrical Characteristics

NOTE 1: This parameter is defined in accordance with JEDEC Standard 65.

NOTE 2: Only valid within the VCO operating range.

NOTE 3: Defined as skew between outputs at the same supply voltage and with equal load conditions.

Measured at the output differential cross points.

NOTE 4: Spread Spectrum clocking enabled.
