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 -20°C to
+70°C 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.
