Note 1: Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the
device. These ratings are 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.




Description

The M685 is a dual SAW, selectable frequency VCSO 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 M685-01 is available in a range of center frequencies from 125 to 175 MHz.

The M685-02 provides 500 to 700 MHz. Guaranteed minimum pull-range of ±120 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 M685 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).
