LCC Surface Mount Package
(9 x 14mm)
The M655 Series of Voltage Controlled SAW
Oscillators is a low cost solution for many Telecom
applications. An internal SAW filter provides jitter
performance of less than 0.5psec (rms).
This device is specified for an operating
temperature range of -40°C to +85°C. A disable
feature forces the output into a static condition by
applying a logic “0” to the clock enable input. The
oscillator is housed in a hermetically-sealed,
leadless surface mount package.
The M655 Series of VCOs is available over an
output frequency range of 155MHz to 900MHz.
The device is most suited for phase-locked loop
applications as well as clock and data recovery
circuits.
