This parameter is measured as an average over a 1 us duration, with a crystal center frequency of 14.31818MHz
Probes are placed on the pins and measurements are acquired between 0.4V and 1.4V.
This is required for the duty cycle on the REF clock out to be as specified. The device will operate reliably with input duty cycles up to 30/70 but the REF clock
duty cycle will not be within data sheet specifications.
Probes are placed on the pins, and measurements are acquired at 0.9V.
This measurement is applicable with Spread ON or spread OFF.
The time specified is measured from when all VDD
’
s reach their respective supply rail (3.3V and 1.8V) till the frequency output is stable and operating within the
specifications
When Xin is driven from and external clock source.
