High-stability crystal oscillator

16 July 2014 Analogue, Mixed Signal, LSI

IQD’s new IQXT-210 series TCVCXO (temperature and voltage controlled crystal oscillator) offers frequency stabilities down to ±0,14 ppm over the full industrial temperature range of -40°C to 85°C.

While exhibiting performance levels approaching that of OCXOs, the device is packaged in an 8-pad, 5 x 3,2 mm housing.

Powered from a 3,3 V supply, the oscillator has a typical current draw of only 12 mA dependent upon the frequency, which can be specified between 10 MHz and 50 MHz. Eleven standard frequencies are initially offered, including 12,8 MHz, 19,2 MHz and 26,0 MHz.

Output can be specified as either HCMOS, 15 pF load or clipped sine, into a 10 kΩ load. The IQXT-210 can be specified to include various pulling range options, from ±5 ppm to ±10 ppm and also ±10 ppm to ±15 ppm. This enables the frequency to be adjusted by a fixed amount for various applications and also allows for the oscillator to be used remotely.

The device is primarily designed for low-power consumption applications such as femtocells, smart wireless devices, fibre-optic networking (PON), microwave satellite communications, LTE/4G base stations, backhaul infrastructure, packet transport network (PTN) computer networking, RF modules, Wi-Fi and test and measurement equipment.
