Product Brief

M624

VOLTAGE CONTROLLED SAW OSCILLATOR

GENERAL DESCRIPTION

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.
