... Cycle–Cycle Jitter The MPC993 continuously monitors the two input signals to identify faulty reference clocks. Upon identification of a faulty input clock (input clock stuck HIGH or LOW for at least 3 feedback clock edges), an input bad flag will be set and the device will automatically switch from the bad reference clock input to the good one ...

... Alarm_Reset pin being negated. If both of the input signals go bad simultaneously the MPC993 PLL will lose lock and the VCO will drift to an indeterminate frequency. Once the MPC993 switches from a bad clock it will continue to use the new clock until the Alarm_Reset pin is asserted. The device will not switch back to a “ ...
