Ovened crystal delivers ±5ppb stability in 14 x 9 mm footprint

April 23, 2014 // By Graham Prophet
In an industry standard package measuring 14 x 9.0 mm and with a height of 6.5 mm, IQD’s IQOV-162 series OCXO provides a frequency stability down to ±5ppb (parts per billion) over the full industrial temperature range from –40 to 85C.

This model is available in a frequency range from 10 to 100MHz. Operating from a 3.3V supply, the IQOV-162 consumes 600 mA of current during warm up and takes less than 5 minutes to be within <100ppb of the final specification; it uses 300 mA max at steady state @25 degrees C.

The output can be specified as either HCMOS, 15 pF load or sinewave, into a 50 Ohms load. As well as offering phase noise performance better than -150 dBc/ Hz @ 1kHz offset, ageing performance is also extremely good at less than ±500 ppb 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 ±3 ppm to ±8 ppm.

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.
