SY89426 Overview
Micrel's SY89426 Multi-Output Phase Locked Loop (PLL) is a SONET pliant 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, the input reference clock is retimed and provided as a TTL/CMOS patible output, which may be disabled to minimize...
