General Description

The SY87729L is a complete rate independent frequency synthesizer integrated circuit.

From a single reference source, this device generates a differential PECL reference frequency for Micrel's SY87721L 10Mbps to 2.7Gbps combined CDR and CMU.

The SY87729L generates an exactly correct reference frequency for common data transport protocols.

Overview

SY87729L 3.3V AnyClock®, 10MHz to 365MHz Fractional N Synthesizer.

Key Features

  • AnyClock®.
  • Fractional synthesizer from 10MHz to 365MHz from a single 27MHz reference oscillator.
  • Generates exactly the correct frequency for common transport protocols with or without FEC.
  • Directly enables SY87721L 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.
