Notes for preceding table:

Measured into fixed 2 pF load cap. Input to output skew is measured at the first output edge following the corresponding input.

Measured from differential cross-point to differential cross-point. This parameter can be tuned with external feedback path, if present.

All Bypass Mode Input-to-Output specs refer to the timing between an input edge and the specific output edge created by it.

⁴This parameter is deterministic for a given device

Measured with scope averaging on to find mean value. DIF_IN slew rate must be matched to DIF output slew rate.

^6.t is the period of the input clock

⁷Measured as maximum pass band gain. At frequencies within the loop BW, highest point of magnification is called PLL jitter peaking.

Guaranteed by design and characterization, not 100% tested in production.

Measured at 3 db down or half power point.

¹⁰Duty cycle distortion is the difference in duty cycle between the output and the input clock when the device is operated in bypass mode.

¹¹Measured from differential waveform
