Voltage Controlled SAW Oscillator

The M675 is a VCSO (Voltage Controlled SAW Oscillator) frequency source for low-jitter clock generation. An integrated SAW (surface acoustic wave) delay line implements the high-Q VCO (voltage controlled oscillator) function, which results in low output phase noise and very low jitter. The M675-01 is available in a range of center frequencies from 125 to 175 MHz. The M675-02 provides 500 to 700 MHz. Guaranteed minimum pull-range of ±100 ppm meets GbE requirements. (It also fully satisfies ±50 ppm minimum pull-range specification commonly required.) Industry-standard Kvco (VCO Gain) provides full replacement compatibility. The M675 is well suited for phase-locked loop implementations, clock and data recovery circuits, and other timing applications in telecom and optical fiber networking systems (e.g., SONET/SDH).
