CVSS-945X-100.000 The CVSS-945X-100.000 is a 100MHz Voltage Controlled Crystal Oscillator (VCXO) from Crystek Corporation, delivering a True SineWave output with +5dBm drive into 50 ohms. Built on the CVSS-945 platform, this oscillator achieves a phase noise floor of -172.9 dBc/Hz at 1 MHz offset — corresponding to femtosecond-level integrated jitter. With 20ppm minimum APR pullability, sub-harmonic-free output, and a compact 9x14mm SMD package, it serves as a precision reference for PLL-based synthesizers, test equipment, radar systems, satcom transponders, and any application demanding ultra-low phase noise with voltage-controlled frequency adjustment.
