The CFPV-2365 is a high-frequency voltage-controlled crystal oscillator (VCXO) designed for time multiplexing applications in SDH STM-4 and SONET STS-12 synchronous digital trunklines. According to its manufacturer, it is one of the first 622.08-MHz VCXOs to be implemented using bulk- acoustic-wave (BAW) crystal technology. The company also provides conventional surface-acoustic-wave (SAW) devices with a superior combination of frequency stability and voltage control ("frequency pulling"). Meanwhile, it combines a frequency stability of ±20 ppm from 0°C to 70°C, or ±30 ppm from −25°C to +85°C, with frequency pullability between ±80 and ±120 ppm. Its jitter is less than 2 ps between 12 kHz and 150 MHz from the output frequency. Operating from a 3.3-V power supply, it comes in an industry-standard hermetically sealed metal package that measures 20.7 by 20.7 by 9.9 mm. It's available now priced from $48 each, depending on specification, in 10,000-unit quantities.
