843N3960I - Block Diagram
Description
The 843N3960I is an LVPECL clock synthesizer. The 843N3960I can synthesize 100MHz, 125MHz, 156.25MHz, and 212.5MHz from a single 25MHz crystal or reference clock. Utilizing an external loop filter capacitor, the 843N3960I is capable of holdover mode when the main reference clock becomes unstable, making this ideal for redundant timing applications.
