New low-power miniature TCXO available in five versions

Housed in a small 2mm x 2.5mm x 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 -40C to 85C with a clipped sinewave output. Operating from 1.8 to 3.3V, the new range is available in three versions: TCXO, VCTCXO and 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, says the company. 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 ideal for demanding GPS mobile applications including portable navigation devices as well as Wi-Fi, WiMax, WLAN and Ethernet applications, says the company.
