Notes:
1. Measured into fixed 2 pF load cap. Input-to-output skew is measured at the first output edge following the
corresponding input.
2. Measured from differential cross-point to differential cross-point.
3. This parameter is deterministic for a given device.
4. Measured with scope averaging on to find mean value.
5. All Bypass Mode Input-to-Output specs refer to the timing between an input edge and the specific output edge created
by it.
6. Measured as maximum pass band gain. At frequencies within the loop BW, highest point of magnification is called PLL
jitter peaking.
7. Measured at 3 db down or half power point.
