CO-760 PS SERIES LOW PROFLE, SURFACE MOUNT
OVEN CONTROLLED CRYSTAL OSCILLATORS (OCXOs)
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" (20.45mm 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 -20ºC to +70ºC 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.
The Vectron International group designs, manufactures and markets frequency generation and control products using the very latest techniques in both standard crystal and surface acoustic wave (SAW) based designs from DC to microwave frequencies. Products include crystals and crystal oscillators; SAW filters and components; and clock and data recovery products used in telecommunication and data communication applications.
