M655 Series
Voltage Controlled SAW Oscillators
M655 Series
Performance Specifications
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
FEATURES
This device is specified for an operating temperature range of -40C to +85C. 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.
Output Frequencies at 155MHz to 900MHz Low Phase Jitter, 0.5psec (rms) typical 3.3 Volt Supply Operation Complementary Outputs Output Disable Feature LCC Surface Mount Package (9 x 14mm)

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.

Micro Networks has designed the M655 device as a sealed unit. The package is 100% tested for seal defects. Aqueous, solvent, or other wash type cleaning methods is acceptable for this device.
