New miniature Low Power TCXO/VCTCXO launched by IQD

26 MAY 2015

Housed in a small 2.0 × 2.5 × 0.8mm ceramic package, IQD’s new IQXT-260 series of digitally compensated TCXOs, employs an analogue ASIC for the oscillator and a high order temperature compensation circuit that provides a smoother signal. With a maximum current consumption of only 2mA, the IQXT-260 offers stabilities down to ±0.5ppm over an operating temperature range of -40 to 85°C with a clipped sinewave output. Operating from 1.8 to 3.3V, the new range is available in three versions: TCXO, VCTCXO & TCXO with enable/disable function, all across a frequency range of 10 to 52MHz. The version with the enable/disable option only requires a standby current of typically <0.01µA, which is ideal for battery operated equipment. As frequency bands such as 2.4GHz become overcrowded and the bandwidths need to be narrower, the precise signal and tighter frequency stability of a TCXO solution is ideal plus frequency slope and perturbation specifications can be customised to suite application requirements. The IQXT-260's high stability, low power consumption, small footprint and powerful compensation method makes this new TCXO ideally suited for demanding GPS mobile applications including Portable Navigation Devices as well as Wi-Fi, WiMax, WLAN and Ethernet applications.
