Integrated Circuit Systems

The M650 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 M650 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.
