| Product Data Sheet CO-760PS Series Surface Mount Oven Controlled Crystal Oscillators Features * Frequencies Available from 4.8 MHz to 61.44 MHz. * Stability as high as 2 x 10 -8 over -20C to +70C * Aging: 5 x 10 -9 / day to 5 x 10 -10 / day * Package: 0.8" x 0.8" x 0.6" (20.5 x 20.5 x 15.2 mm) * Low Profile, Surface Mount Design * Supply Voltage: +5 volts or +3.3 volts Applications * Telecommunication Systems * Wireless Communication Equipment * Data Communications * Instrumentation Description Vectron International has introduced a series of low profile, surface mount, oven controlled crystal oscillators (OCXOs) available in frequencies from 4.8 MHz to 61.44 MHz. The model CO-760PS provides exceptionally low aging rates and high temperature stabilities and is packaged as a surface mount device (SMD), measuring 0.8" x 0.8" x 0.6" (20.5mm x 20.5 mm x 15.2 mm). The oscillators are available with SC or AT cut crystals and provide an aging rate as low as 5 x 10-10/day with temperature stabilities from 2 x 10-8 over -20C to +70C and operate from a +5V supply steady power of 1watt. The phase noise floor at 50 kHz is - 140 dBc/Hz for AT cut crystals and - 145 dBc/Hz for SC types, depending on the output frequency. The product finds application in telecommunications, data communications, frequency synthesizers, timing, navigation, telemetry and instrumentation systems.
