GENERAL DESCRIPTION

The M670 is a VCSO (Voltage Controlled SAW Oscillator) frequency source for low-jitter clock generation. Its integrated SAW (surface acoustic wave) delay line provides low phase jitter. The M670 is available in a range of center frequencies. Minimum pull-range is ±50 ppm (wider pull-range available).

The M670 is well suited for phase-locked loop implementations, clock and data recovery circuits, and other timing applications for the telecom and optical fiber networking markets (e.g., OC-48, OC-192).
