Fort Myers, Florida — FOX331 series, HCMOS, temperature-controlled oscillators (TCXOs) and voltage-controlled temperature-controlled oscillators (VCTCXOs), from Fox Electronics, feature Stratum III stability. They are designed to comply with the Telcordia GR 1244 specification, which requires a daily stability of 0.37 ppm and a frequency stability of less than 4.6 ppm for 20 years.
Featuring a small profile of 7.0 mm (L) x 5.0 mm (H) x 2.0 mm (W) as well as 3.3 V operation, this oscillator family is ideal for telecom network applications including data and voice transfer, base stations, telecom infrastructure and network synchronization.
The series is available in frequencies of 10 MHz to 20 MHz and offers an overall frequency stability of ±4.6 ppm as well as ±0.28 ppm over a temperature range of -20 to +70 degrees Celsius and ±0.37 ppm over a temperature range of -40 to +85 degrees Celsius. Storage temperature range is -55 to +125 degrees Celsius.
In addition, the oscillators offer a phase noise of -120 dBc/Hz at an offset of 100 Hz, -140 dBc/Hz at an offset of 1 kHz and of -148 dBc/Hz at an offset of 10 kHz. The series has a source current (IOH) and a sink current (IOL) of 6 mA. Input current (IDD) is 6 mA.
The RoHS-compliant FOX311 TCXO/VCTCXOs are packaged on tape and reel and are available for low volume programs.
A datasheet is available.
