SY87739L Datasheet (Micrel Semiconductor)

SY87739L, Fractional-N Synthesizer

The SY87739L is a complete rate independent frequency synthesizer integrated circuit.

From a single reference source, this device generates a differential PECL output frequency from 10MHz up to 729MHz The SY87739L generates an exactly correct reference frequency for common data transport protocols.

SY87739L Features

* Protocol transparent fractional-N synthesizer from 10MHz to 729MHz from a single 27MHz reference oscillator

* Generates exactly the correct frequency for common transport protocols with or without FEC

* Directly enables SY87721L CDR to lock onto any data rate within its ran
