Integrated Circuit Systems, Inc. Preliminary Information M685 nFOUT DUAL SAW, SELECTABLE FREQUENCY VCSO PIN ASSIGNMENT (5 x 7.5mm SMT) FOUT VCC GENERAL 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...
