Product details

Automotive-grade MEMS clock at 66.6666 MHz

The DSC1121AI2-066.6666 is a MEMS-based XO (Standard) oscillator from Microchip Technology, delivering a 66.6666 MHz CMOS output with ±25 ppm frequency stability. Its AEC-Q100 qualification and -40°C to +85°C temperature range make it suitable for automotive electronic modules, industrial controllers, and networking equipment that require a precise reference clock.

Supply rail flexibility and output control

Operating from 2.25V to 3.6V, this oscillator can be powered directly from a 2.5V, 3.0V, or 3.3V rail without an intermediate LDO.

Package fit for standard 7x5 mm footprint

Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm, this oscillator drops into the common 7x5 mm oscillator land pattern.

Frequently asked questions

Is the DSC1121AI2-066.6666 AEC-Q100 qualified?

Yes, it is rated AEC-Q100. That means it has passed automotive-grade reliability testing and comes with PPAP documentation — required for OEM audit compliance in production vehicle programs.
