OCXO 139

Low Noise, Stratum 3E, DIL Oven-Controlled Crystal Oscillator (OCXO)

CTS Model 139 is a high-performance oven-controlled crystal oscillator (OCXO) suitable for applications requiring Stratum 3E performance. Its low, -170 dBc/Hz noise floor makes it ideal for use in not only SONET/SDH and packet-based telecommunication applications and but also instrumentation and test equipment, synthesizers, radar and satellite communications. Using an internal oven, the series 139 OCXO keeps its quartz resonator crystal at ideal temperatures which increases stability and accuracy. With fewer temperature fluctuations, the series 139 will experience fewer short-term phase shifts resulting in less phase noise that would otherwise degrade the quality of the signal.
