IQD’s New Miniature VCTCXO launched at Embedded Show delivers class leading frequency stability

Posted: 13th March 2017

IQD’s New Miniature VCTCXO launched at Embedded Show delivers class leading frequency stabilityIQD’s latest Voltage Controlled Temperature Compensated Crystal Oscillator (VCTCXO) offers frequency stabilities down to ±0.28ppm over the full industrial temperature range of -40 to 85 degrees C in a package measuring only 3.2 x 2.5mm.

As standard, the new IQXT-220 includes voltage control (frequency adjustment option) that gives on-board frequency tuning between ±10ppm to ±15ppm. This tuning is enough to remove the effect of reflow soldering during manufacturing, plus an allowance for locking to a PLL and also ageing calibration for many years. However some customers prefer not to have the function for simplicity of design so it can be specified without this option.

The new model is housed in a miniature 4-pad 3.2 x 2.5mm ceramic package and powered from a 3.3v supply with a maximum current draw of only 3mA @25°C when driving 10kohms into 10pF load. Ten standard frequencies are available including 10.0MHz, 12.8MHz, 19.2MHz and 38.88MHz with a Clipped Sine output and 10KΩ//10pF load. Phase noise performance is -140dBC/Hz at 1kHz offset whilst aging per day is down at ±20ppb.

The new model is primarily designed for low power consumption applications which require a high stability frequency source such as Femto & Pico cells, 4G/LTE, Smart Wireless Devices, Fibre Optic Networking (PON), Backhaul Infrastructure, RF Modules, Wi-Fi, WLAN/WiMax and Test & Measurement Equipment.

All devices are RoHS compliant, reflow soldering compatible and supplied on tape and reel or cut tape. Full data sheets are available on IQD’s website at www.iqdfrequencyproducts.com
