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

Description

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.

Features

  • s Single chip source for 622.08MHz and 155.52MHz clocks s 622.08MHz output is differential PECL, 155.52MHz output is single-ended PECL s TTL/CMOS compatible inputs and reference output s SONET compliant jitter performance (≤0.01UI) s Choice of three reference frequencies s Only 395mW (typ) s Complies with Bellcore, CCITT and ANSI standards s Single +5 volt power supply s Fully compatible with industry standard 10KH I/O levels s Available in 28-pin PLCC package Precision Edge®.
