High-frequency OCVCSOs aim to improve phase noise performance
From IQD Frequency Products comes a range of high frequency oven controlled voltage controlled SAW Oscillators (OCVCSOs). Three frequencies are currently available in the OCVCSO series, 400MHz, 800MHz and 1.2GHz and they come in a 25.4 x 22 x 13.2mm industry standard SMD package.
The OCVCSOs have a noise floor of 10dB to 15dB lower than an OCXO at the same frequency, which IQD Frequency Products says enables a much improved phase noise performance for applications such as radar detection systems. The 400MHz OCVCSO frequency is generated from a fundamental high-Q SAW resonator, whereas the 800MHz and 1.2GHz are generated using high frequency fundamental SAW resonator with a low noise frequency doubler.
Multiplying the frequency only once enables superior phase noise performance, down to -168dBc/Hz at the floor level and jitter between 10kHz and 100MHz of <10fs. The 400MHz OCVCSO, being based on a fundamental frequency, has a phase noise performance of -174dBc/Hz at the floor level and jitter of <5fs.
With stabilities down to ±2ppm over an operating temperature range of 0 to +50 degrees C and ageing of ±6ppm max over 10 years these new lightweight OCVCSOs, weighing only 8g, are suitable for use for radar, simulators, communication systems and unmanned aerial vehicles.
The OCVCSO operates from a 5V supply with power consumption of between 0.8W and 1W, has a 50-Ohm sine output and a voltage control option, which enables the frequency to be pulled by a minimum of ±6ppm.
IQD is part of the Würth Elektronik eiSos group, one of the leading European manufacturers of passive components. With active customers in more than 80 countries, IQD offers a comprehensive frequency product range, from low cost commercial grade product to that used in high reliability industrial and automotive applications including: quartz crystals, clock oscillators, AEC-Q200 crystals and oscillators, VCXOs, TCXOs, OCXOs, GPS disciplined OCXOs, and rubidium oscillators.
