ADS1293: Data converters forum

Part Number: ADS1293

We are looking for a tiny 4.096 MHz oscillator or crystal for use with the ADS1293. We are using the part in a small device. Are you aware of a much smaller alternative to a part similar to the example below? Seems like there must be something as this is a significant limitation to using the ADS1293 in small devices.

Hi Brian,

Thank you for your post!

I'm not aware of any other oscillator or crystal much smaller than the SMD crystal you listed. Our reference design's crystal oscillator has approximately the same dimensions as you have shown, albeit a little taller.

The ADS1293 can also operate with an external 409.6 kHz oscillator through the bi-directonal CLK pin. The options for external oscillator is wider compare to the SMD crystal. One example is the oscillator ultra-small MEM oscillator DSC60xx (see link for Digikey below).

Thanks.
