Product details

MEMS-based 33 MHz XO with ±50 ppm stability

The DSC1121DL1-033.0000T: Unlike a quartz crystal oscillator, the MEMS resonator is less susceptible to vibration and shock, and the part's supply voltage spans 2.25V to 3.6V — a single rail covers 2.5V, 3.0V, and 3.3V logic without a separate regulator.

Enable/Disable and supply flexibility

Maximum supply current is 22 mA, typical for a 33 MHz CMOS-output oscillator; the wide input range means the same BOM line works across 2.5V, 3.0V, and 3.3V rails without a voltage translator.

Frequently asked questions

What is the difference between the DSC1121DL1-033.0000T and a standard quartz oscillator?

The DSC1121 uses a MEMS resonator instead of a quartz crystal. MEMS oscillators typically offer better shock and vibration resistance, faster start-up time, and a wider supply voltage range. The ±50 ppm stability is comparable to a standard quartz XO.
