Precision OCXO comes in subminiature, low-profile package.

Press Release Summary:

Miniature precision Oven Controlled Crystal Oscillator (OCXO), RFX OS265 - 8.5, comes in 20.5 x 12.9 x 8.5 mm, shielded, metal DIL case. Incorporation of SC cut resonator produces minimum long term ageing (±0.05 ppm per year max), accelerated warm up, and accuracy from ±0.005 ppm with phase noise better than -140 dBc/Hz at +100 Hz offset. Along with quiescent current of 110 mA typ for +5 Vdc supply, module has 15 pF CMOS output and supply range of 3.3 to +12 Vdc.

On Behalf of RFX Ltd Laptech Precision Inc. announce the release of a sub-miniature low profile precision OCXO

Livingston Scotland - RFX, a British manufacturer of Precision Quartz Oscillators, today announce the release of their miniature precision Oven Controlled Crystal Oscillator type OS265 - 8.5.

The module, packaged in a shielded metal DIL case, only 8.5mm tall, provides exceptional performance combining high accuracy and low ageing with excellent phase noise and is the smallest precision OCXO in the world with this combination of high quality attributes.

The incorporation of an SC cut resonator, custom designed for RFX and manufactured by their Canadian subsidiary, produces minimum long term ageing, fast warm up, accuracy from ±0.005ppm with phase noise better than -140dBc/Hz at +100Hz offset making this new OCXO a world leader in its class.

The OS265 - 8.5 module sets a new standard in miniature precision OCXO's exceeding specifications for traditionally large units and expanding the useful applications for this product group. It has been developed for use in Base Stations, Wireless Networks, System Synchronization systems, Instrumentation, Critical timing and Calibration applications and with low weight and minimum power consumption make it ideal for portable applications.

Specific features include:
Package: DIL, screened, metal case (20.5 x 12.9 x8.5.)mm
Output: CMOS 15pF
Supply voltage: 3.3Vd.c. to +12Vd.c.
Quiescent current: 110mA typical for +5Vd.c. supply
Accuracy: from ±0.005ppm
Trim range: ±0.5ppm min.
Phase noise: -140dBc/Hz at +100Hz typical
Ageing: ±0.05ppm per year max.

RFX manufacture a complete range of precision oscillators from 1MHz to 2.4GHz including TCXO, VCXO, PLL and GPS modules.
