New ultra miniature OCXO from IQD delivers ±5ppb stability in a 14 x 9mm package


In an industry standard package measuring just 14 x 9.0mm and with a height of only 6.5mm, IQD’s new IQOV-162 series OCXO provides a frequency stability down to ±5ppb (parts per billion) over the full industrial temperature range from –40 to 85 degrees C.

In addition to this exceptional size/performance ratio the new model is available in a very wide frequency range from 10 to 100MHz. Operating from a 3.3V supply voltage, the IQOV-162 consumes 600mA of current during warm up and takes less than 5 minutes to be within <100ppb of the final specification and 300mA max at steady state @25 degrees C.

 The output can be specified as either HCMOS, 15pF load or Sinewave, into a 50 Ohms load. As well as offering phase noise performance better than -150dBc/Hz @ 1kHz offset, ageing performance is also extremely good at less than ±500ppb per year.

Variants can be specified to include voltage control to enable the frequency to be adjusted for correction over time and remotely with a pullability range of ±3ppm to ±8ppm.

The IQOV-162 series is primarily designed to be used in applications such as CDMA base stations, femtocells, optical networking, 3G & 4G LTE, Ethernet, SoNET/SDH, ATM backplanes, SATA and satellite communications, or whenever a very low profile OCXO is required.

IQD’s products are specified by leading manufacturers in the aerospace, automotive, communications, computing, consumer, industrial, medical and military industries throughout the world. We work with several premier chip-set designers on a variety of key projects and hold approvals on a number of products including high specification oscillators. Our full range of products is available direct from all of our offices or via our extensive worldwide distribution and representative network. Full contact details are available on our website at
