Miniature Low Phase Noise OCXO measures 9.7 x 7.5 mm.

Press Release Summary:




Supplied in 4-pad plastic package with fiberglass base, IQOV-71 series comes in standard frequencies of 10, 12.8, 19.2, 20, 24.576, 25, 30.72, 38.88, 40, 49.152, and 50 MHz. Power consumption is <1 W typ during warm up, which takes ~3 min, and <0.4 W in steady state, and low frequency stabilities reach down to ±10 ppb over -20 to +70°C operating range or ±20 ppb from -40 to +85°C. HCMOS or Clipped sinewave output, with operating voltages specified at 3.3 or 5.0 V, are standard.



Original Press Release:



New Miniature OCXO from IQD Measures Only 9.7 x 7.5mm



IQD’s latest Oven Controlled Crystal Oscillator (OCXO), the IQOV-71 series, is housed in 4-pad plastic package with a fibre glass base measuring only 9.7 x 7.5mm. Despite the ultra-small size, the new model offers very low frequency stabilities down to ±10ppb over an operating temperature range of -20 to 70 degrees C or ±20ppb over -40 to 85 degrees C making it a class leader for this type of high performance device.



Standard frequencies available are 10MHz, 12.8MHz, 19.2MHz, 20MHz, 24.576MHz, 25MHz, 30.72MHz, 38.88MHz, 40MHz, 49.152MHz and 50MHz which will satisfy most typical applications. Other frequencies in the range 5MHz to 50MHz can be developed for commercially viable quantities. Critically, power consumption is typically less than 1 Watt during warm up which only takes approximately 3 minutes and less than 0.4Watts once the device has reached steady state. Frequency ageing is less than 2ppb per day and a maximum of 3ppm over a 10 year period.



The IQOV-71 offers either a standard HCMOS or Clipped sinewave output, with operating voltages specified at either 3.3V or 5.0V. Low phase noise performance is assured with figures of -152dBC/Hz at 10kHz offset and only -153dBc/Hz at 100kHz from the carrier. Unusually for this type of device, the G-sensitivity is also good at <2ppb/G making the design suitable for applications such as military radios and airborne applications.



In order to maximise flexibility there is an option to specify external frequency adjustment by the application of a variable control voltage that allows for crystal ageing as well as changes in the circuit conditions. This variation is also extremely linear being <1% as against a more typical 5%.



This part is intended for a wide range of applications including Picocells for the ever increasing rage of wireless applications, satellite communication, broadcasting, microwave and instrumentation such as frequency counters and analysers.
