New miniature Low Power TCXO/VCTCXO launched by IQD at IMS 2015
Posted: 19th May 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.
