M624

The M624 is a VCSO (Voltage Controlled SAW Oscillator) frequency source specifically designed for high-speed SONET/SDH applications for rates up to OC-768. Its integrated SAW (surface acoustic wave) delay line provides excellent phase noise performance and spectral purity, while requiring a low supply voltage (+3.3V). An extremely linear tuning range makes the M624 especially suited for phase-locked loop applications, which are extensively used in timing circuits and clock and data recovery in fiber-linked data systems. The SMT VCSO's small size and minimal power requirements make it ideal for the miniturization applications that are emerging, without sacrificing performance.
