Miniature TCXOs consume 2 mA max.

Press Release Summary:

Housed in 2.0 x 2.5 x 0.8 mm ceramic package, IQXT-260 Series employs analog ASIC for oscillator and high order temperature compensation circuit that provides smooth signal. Digitally compensated devices offer stabilities down to ±0.5 ppm over operating temperature range of -40 to +85°C with clipped sinewave output. Operating from 1.8–3.3 V, series is available in 3 versions: TCXO, VCTCXO, and TCXO with enable/disable function, all across frequency range of 10–52 MHz.

Original Press Release:

New Miniature Low Power TCXO/VCTCXO Launched by IQD at IMS 2015

Housed in a small 2.0 x 2.5 x 0.8mm ceramic package, IQD’s new IQXT-260 series of digitally compensated  TCXOs,  launching at IMS 2015, 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.

Full details will be available at IQD’s booth 2915 at IMS 2015.
