M675S02 Datasheet Rev 1.0 Revised 07Feb2012 Integrated Device Technology, Inc. ● N e t c o m T i m i n g ● www.idt.com ● tel (774) 348-1600 M675S02 SIGE SINGLE FREQUENCY VCSO Preliminary Datasheet GENERAL DESCRIPTION The M675S02 is a single frequency/single output SAW-based VCSO for low-jitter clock generation. The SAW (surface acoustic wave) delay line serves as a high-Q resontaor and the low noise SiGe VCSO IC provides a low noise floor and low 1/f phase noise. The combination of the SAW delay line and the custom IC result in very low phase noise and jitter performance. The M675S02 is available in frequencies from 500 to
1000 MHz with a guaranteed minimum pull-range
of ±120 ppm. Industry-standard Kvco (VCO Gain) provides full replacement compatibility for most designs. The M675S02 is well suited for phase-locked loop applications, clock and data recovery circuits and other timing applications in telecom and optical fiber networking systems.
