GM5351A - CMOS Clock Generator

General Description

The GM5351A is an I2C configurable clock generator that is ideally suited for replacing crystals, crystal oscillators, phase-locked loops (PLLs), and fanout buffers in cost-sensitive applications.

The GM5351A can generate any frequency up to 250MHz on each of its outputs with 0ppm error.

Key Features

  • Generates up to 3 non-integer-related frequencies from 2.5KHz to 250MHz.
  • I2C user definable configuration.
  • Exact frequency synthesis at each output (0 ppm error).
  • Optional clock input (CLKIN).
  • Low output period jitter:.
