   M660-02 output frequencies from 500 to 700 MHz (Specify center frequency at time of order)
• Two integrated SAW devices
• Selectable output frequency
• Supports multi-rate optical interface requirements
• Low phase jitter 0.37ps rms typical (12kHz to 20MHz)
• Low phase noise -70dBc/Hz @ 1kHz offset
• Differential 3.3V LVPECL output
• Single 3.3V power supply
• Small 9 x 14 mm SMT (surface mount) package

The M660-01 is a dual SAW, selectable frequency VCSO 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 M660-01 is available in a range of center frequencies from 125 to 175MHz. The M660-02 is available in a range of center frequencies from 500 to 700MHz. Minimum pull-range is +50 ppm (wider pull-range is available). The M660 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., OC-48, OC-192).
