Miniature Low-Power TCXO/VCTCXO

Housed in a small 2.0 × 2.5 × 0.8 mm ceramic package, IQD Frequency Products’s new IQXT-260 series of digitally compensated  TCXOs employs an analog ASIC for the oscillator and a high-order temperature compensation circuit that provides a smoother signal. With a maximum current consumption of only 2 mA, the IQXT-260 offers stabilities down to ±0.5 ppm over an operating temperature range of –40° to 85°C with a clipped sinewave output. Operating from 1.8 to 3.3 V, the new range is available in three versions: TCXO, VCTCXO, and TCXO with enable/disable function, all across a frequency range of 10 to 52 MHz. The version with the enable/disable option only requires a standby current of typically <0.01 µA, which is ideal for battery operated equipment.tcxo-vctcxo-IQD

As frequency bands such as 2.4 GHz 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 customized 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.
