Product details

The DSC1121AI2-033.3330T is a MEMS-based XO (Standard) oscillator producing a 33.333 MHz CMOS output — a direct drop-in for quartz-based clock sources in digital systems. Rated over -40°C to 85°C with ±25 ppm frequency stability, it holds timing margin across industrial temperature swings without the warm-up drift of a quartz crystal.

Operates from 2.25V to 3.6V — covers 2.5V and 3.3V logic rails without an external regulator. Housed in a 6-VDFN exposed pad package (7.00mm x 5.00mm, 0.90mm seated height).

Frequently asked questions

What is the output type of DSC1121AI2-033.3330T?

The output is CMOS — a standard digital logic level that drives most MCU and FPGA clock inputs directly without a level translator.

What voltage does DSC1121AI2-033.3330T require?

It accepts a supply voltage from 2.25V to 3.6V, covering both 2.5V and 3.3V rails commonly found in industrial designs.
