New frequency controlled crystal oscillator

19 September 2007 Electronics Technology

Vectron International has expanded its C3430 frequency controlled crystal oscillator (FCXO) family for use in wireline infrastructure, test and measurement, military applications and wireless infrastructure such as GSM, CDMA and W-CDMA base stations and point-to-point radio. Leveraging an integrated crystal-based phase locked loop circuit, the latest C3430 FCXO enables the conversion of one input frequency into as many as four independent output frequencies to simplify clock distribution, while its plug-and-play functionality helps to reduce total cost of ownership and research and development cycles.

The C3430 frequency converter offers output frequencies from 10 to 700 MHz in a unique oscillator design, leveraging a proven FR4 surface mount packaging design. It features low jitter of less than 0,20 ps RMS across 12 kHz to 20 MHz and less than 0,70 ps RMS across 10 Hz to 100 kHz. The converter features phase noise performance ranging from -75 dBc @10 Hz to -150 dBc @100 kHz. It is available in a 13 x 20 mm package and operates in temperatures between -40 and +85°C.
