MICRO CRYSTAL has launched a new TM-2220-C7 highly stable temperature compensated oscillator 32.768 kHz (TCXO) with integrated X-Tal and CMOS clock signal output.

TM-2220-C7 is a plug and play temperature compensated frequency reference for applications where reliable and accurate oscillator is needed without frequency jump.

Combining minimal foot print (3.2 x 1.5 x 0.8 mm), only 4 connections and outstanding performances with 1.5 µA maximum current consumption associated to tight frequency stability of ± 5 ppm over full industrial temperature range, this factory calibrated device is embedded in a hermetically sealed compact reflow solderable DFN [1] package.

This fully embedded device achieves significantly better stability performances then separate components on a PCBA. Moreover, it does not require any oscillator adjustment during OEM design phase, minimizing integration constraints thus lowering development cost and time to market.

TM-2220-C7 TCXO low power module with operating voltage range of 1.1 to 3.63 V is designed for high volume and cost sensitive applications with tight space constraints where superior stability and extended operation life are required. It is ideal for asynchronous clocking in battery operated devices like IoT, healthcare, wearables, metering and automotive.

The part is RoHS compliant and AEC-Q200 qualified which facilitates new design-in.

With Micro Crystal improvements and miniaturization of this oscillator, the performance-to-price ratio has been ameliorated – and eventually, any device should benefit from its cutting edge stability and low energy operation.


“The 32.768 kHz TCXO-module TM-2220-C7 is the new milestone in the field of low frequency oscillators. The high stability over temperature is obtained integrating a miniature X-Tal resonator coupled to a TCXO ASIC circuit in closest proximity. The tiny package and the ultra-low power over the common voltage range makes it the frequency reference of choice for multiple applications.”
