Miniature low power TCXO
With a maximum current consumption of only 2.2 mA, the IQXT-270 offers stabilities down to ±0.5 ppm over an operating temperature range of -40 to 85 degrees C with a clipped sinewave output. Operating from 1.8- to 3.0-V, the range is available in three options: TCXO, VCTCXO and TCXO with enable/disable function, all across a frequency range of 13 to 52 MHz. The version with the enable/disable option only requires a standby current of typically <0.01µA, which is ideal for battery operated equipment.
Start-up time from the power mode is only 2ms maximum whilst the VCTCXO (Voltage Controlled Temperature Compensated Crystal Oscillator) option has a pullability of between 6ppm to 30ppm. Typical phase noise at 100 kHz would be -151 dBc/Hz.
The ultra-miniature footprint and low power consumption of the IQXT-270 makes it ideally suited for battery operated applications including GPS mobile applications including portable navigation devices as well as Ethernet, smart wireless devices, Wi-Fi, WiMax and WLAN applications.
