75 MHz MEMS oscillator with automotive qualification
The DSC1121AE2-075.0000T is a 75 MHz XO (Standard) MEMS oscillator from Microchip's DSC1121 series, delivering a CMOS output with ±25 ppm frequency stability over its -20°C to 70°C operating range. Rated AEC-Q100, this oscillator is qualified for automotive applications where reliability under temperature and vibration is critical — think engine control units, infotainment, or ADAS sensor timing. The Enable/Disable function allows the output to be tri-stated, reducing supply current from 35 mA to 22 mA when the clock is not needed — useful for power-sensitive designs that gate the clock during sleep modes.
Supply voltage flexibility and package fit
Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm, the footprint is standard for 7x5 mm oscillators and routes easily on a two-layer board.
Active lifecycle — no end-of-life risk
Supplied in Tape & Reel (TR) packaging, it is ready for automated assembly lines — order quantities are confirmed at RFQ against your BOM volume.
