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.
