Active production, AEC-Q100 qualified MEMS oscillator
The DSC6001JA3B-580K000T is an active-production MEMS-based XO from Microchip's DSC60XXB series, delivering a 580 kHz CMOS output with ±20 ppm frequency stability across the full -40°C to +125°C automotive temperature range.
MEMS resonator vs. quartz: what the rating means for the BOM
This gives the oscillator inherent immunity to vibration-induced frequency shifts and microphonics — a known failure mode for quartz crystals in engine-bay or transmission-mounted modules. The trade-off is that the MEMS die's aging characteristic differs from quartz; the datasheet's long-term stability figure should be reviewed against the application's 15-year life requirement. The 1.71 V to 3.63 V supply range covers 1.8 V, 2.5 V, and 3.3 V logic rails without an external regulator — one BOM line serves multiple voltage domains across a platform.
Package and layout: 4-VLGA footprint
Housed in a 4-VLGA package measuring 2.50 mm × 2.00 mm with a seated height of 0.89 mm. The land pattern is a standard 4-pad LGA — no via-in-pad required, but the small footprint demands tight solder-paste registration during reflow.
