Product details

32 MHz MEMS XO with ±20ppm stability

The DSC1502AI3A-32M00000T: Unlike quartz-based oscillators, the MEMS resonator eliminates crystal aging and vibration sensitivity — a practical advantage for designs that see thermal cycling or mechanical shock on the factory floor or in outdoor telecom enclosures.

Standby power-down and wide supply tolerance

The 2.5V to 3.3V supply range means this oscillator can run directly from a 3.3V rail or a 2.5V core supply without an external regulator, simplifying the power tree.

Frequently asked questions

What is the standby function of the DSC1502AI3A?

The Standby (Power Down) function disables the output and reduces supply current to 1.8µA typical. The oscillator resumes normal operation when the standby pin is de-asserted, with a fast start-up time suitable for intermittent-duty applications.
