Clock Specifications for UMG

In the case of independent CLK boards, the UMG8900 can provide stratum-2A and stratum-3
clock signals. The following specifications has maintained:

Minimum accuracy: the maximum magnitude of the frequency deviation from the nominal frequency for a specified time period (20 years) in the absence of an external reference clock, namely , in the free running state

Maximum frequency off set: the maximum magnitude of the fractional frequency deviation for a specified time period

Pull-in range: the largest frequency bandwidth of the input clock signals that can be
locked

Maximum ti me interval error (MTIE): the largest peak-to-peak delay deviation of a tested clock from a reference clock within a specified test period
