VCXOs Function over Wide Frequency Range
Adding to the XpressO oscillator series, Fox Electronics’ FVXO-PC72 2.5-V LVPECL VCXOs perform in a frequency range from 0.7500 MHz to 1 GHz. The 7-mm × 5-mm components employ a family of proprietary application specific integrated circuits (ASICs), as well as a third order Delta Sigma Modulator (DSM). The devices offer a frequency resolution to 6 decimal places, an absolute pull range (APR) of ±50 ppm, operating temperatures from -20°C to 70°C or -40°C to 85°C, and a tri-state enable/disable function. The RoHS-compliant oscillators are constructed with a gold over nickel termination finish, and have Fox's serial identification system with traceability. Pricing for a FVXO-PC72B XpressO VCXO at 644.5313 MHz in quantities of 1,000 is $6.73.
