SY87739L Datasheet Fractional-n Synthesizer

Manufacturer: Micrel Semiconductor (now Microchip Technology)

Overview: SY87739L Protocol Transparent, 3.3V, 10MHz to 729MHz, Fractional-N Synthesizer.

General Description

The SY87739L is a plete 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 mon data transport protocols.

This is especially important in transponder applications, where a standards pliant protocol data unit must be generated downstream, even in the absence of any signal from the associated upstream interface.

Key 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 range.
  • Exceeds BellCore and ITU jitter generation specifications.
  • Programmable via MicroWire™ interface.
  • Available in 32-Pin ePad-TQFP package.
