M624

VOLTAGE CONTROLLED SAW OSCILLATOR

GENERAL DESCRIPTION

PIN ASSIGNMENT (0.6 x 0.8 inch SMT)

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.
