Note 1:Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the            device. These ratings ard stress specifications only. Functional operation of product at these conditions or any conditions beyond those listed in Recommended Conditions of Operation, DC Characteristics, or AC Characteristics is not implied. Exposure to absolute maximum rating conditions for extended periods may affect product reliability.

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).
