Oscillator delivers tight stability via 1.2V supply
IQD’s IQXT-225 series temperature compensated crystal oscillator (TCXO) requires only a 1.2V supply to deliver excellent frequency stability of ±0.5ppm over an operating temperature range of -30 to 85 degrees C.
Packaged in a tiny 2.0 x 1.6 x 0.7mm hermetically sealed ceramic package, this new model is suitable for use in designs where the life span of the battery is critical, typically Internet of Things (IoT), personal navigation devices (PND), portable test equipment, wearables and wireless communications.
Six commonly used frequencies are available including 16.368MHz, 16.369MHz, 19.2MHz, 26.0MHz, 33.6MHZ and 38.4MHz.
The IQXT-225 has a Clipped Sinewave output and 10k-Ohm//10pF load with a current draw of 1.7mA and a enable/disable function on pin 1 for low power operation; when in disable mode the current draw is 3.0-microA. The new TCXO delivers a phase noise performance of -135dBc/Hz at 1kHz offset and offers a start-up time of 2ms.
Packaging options are ‘tape and r or ‘cut tape’ and a range of standard specifications are available from stock immediately either direct from IQD or via its extensive range of worldwide distributors.
