M655 Series
Voltage Controlled SAW Oscillators
DESCRIPTION
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).
14mm
9mm
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.
FEATURES
Output Frequencies at 155MHz to
900MHz
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.

IR REFLOW PROFILE
Micro Networks has subjected their VCSO component
to various reflow profiles and test conditions for
optimum substrate mounting performance. The
conditions suggested here are recommended
temperature settings for the VCSO device during the
reflow processes. The best case condition for the
device is a slow ramp up to prevent thermal shock
before reaching reflow temperatures of Sn/Pb flux
activated solder with a melting point of 183 degree
Celsius. The M655 device should not see
temperatures above 183 degrees Celsius for an
extended periods beyond 60 seconds. Maximum
peak temperature for the device should not exceed
220 degrees Celsius for longer then 20 seconds.
