General Description
The ICS843N3960I is a LVPECL Clock Synthesizer. The
ICS843N3960I can synthesize 100MHz, 125MHz, 156.25MHz and
212.5MHz from a single 25MHz crystal or reference clock.
Utilizing an external loop filter capacitor, the ICS843N3960I is
capable of holdover mode when the main reference clock becomes
unstable, making this ideal for redundant timing applications.
