Description:

Sonet oc-12/oc-3 clock synthesizer.

SY89426, SONET OC-12/OC-3 CLOCK SYNTHESIZER

Micrel's SY89426 Multi-Output Phase Locked Loop (PLL) is a SONET compliant clock generator providing 622.08MHz, 155.52MHz and retimed reference clock outputs.

The PLL produces low jitter OC-12/STS-12 and OC-3/STS-3 rate clocks from an input reference clock of 38.88, 51.84, or 77.76MHz.

Additionally,
