CDCE62002: VCO Calibration

Part Number: CDCE62002

I am using PLLRESET(2.20) "1-0-1" for VCO Calibration and it cannot be locked infrequently.

However it is improved by adding wait time.

PLLRESET 1-0-1 (When no wait, VCO cannot be locked infrequently.)

PLLRSET 1-0-wait-1  (VCO can always be locked by adding wait time.)

Do I need some wait time?

Best regards.
