80 MHz CMOS MEMS XO for Automotive and Industrial Clock Trees
The DSC6003MI2B-080.0000T is a MEMS-based XO (Standard) from Microchip's DSC60XXB series, delivering an 80 MHz CMOS output with ±25ppm frequency stability across the full -40°C to 85°C range. It operates from a 1.71V to 3.63V supply, drawing a typical 1.3mA — low enough for power-sensitive automotive ECUs or battery-backed systems where every milliamp counts. The Enable/Disable function lets the system shut down the oscillator when the clock is not needed, trimming standby current further.
AEC-Q100 Grade and MEMS Construction
AEC-Q100 qualification means this part has passed the automotive-grade stress tests — temperature cycling, ESD, latch-up — and is rated for under-hood or cabin deployment where reliability is non-negotiable. The MEMS resonator is inherently more shock- and vibration-tolerant than a quartz crystal, which matters on a vehicle's engine bay or a factory floor where mechanical stress can pull a quartz oscillator off frequency.
Housed in a 4-VFLGA package measuring 2.00mm x 1.60mm with a seated height of 0.89mm, this is a compact surface-mount footprint — the 0.50mm pitch LGA pads need careful solder-paste stencil design and a reflow profile that matches the small thermal mass. The part is supplied on Tape & Reel, compatible with automated pick-and-place assembly.
