CVSS-945 Image

The CVSS-945 from Crystek is a true sinewave voltage controlled crystal oscillator (VCXO) that generates frequencies from 10 MHz and 125 MHz. It delivers an output power of more than 5 dBm with harmonics ofunder -25 dBc and has a phase noise floor of -179.7 dBc at 10 MHz. The VCXO requires a 5 V supply and consumes up to 30 mA of current. It is available in an industry standard 9 x 14 mm SMD package. The VCXO operates over an extended temperature range of -40°C to +85°C. Custom specifications are also available. This VCXO is ideal in PLL (Phase Locked Loop) applications.
