SCG2540 generators equivalent, synchronous clock generators.
include an alarm output to indicate Loss of Reference, LOR, or Loss of Lock, LOL. If only one of the references is lost, the unit will disable its phase detector and will.
The SCG2540 is a mixed-signal phase lock loop generating CMOS outputs from an intrinsically low jitter voltage controlled crystal oscillator.
The SCG2540 can lock to one of two possible input reference frequencies at 10 kHz which is selectable using .
