The DSC6001HL2B-012.0000 is a 12 MHz MEMS-based XO from Microchip's DSC60XXB series, delivering a CMOS output with ±25 ppm frequency stability across -40°C to 105°C — the AEC-Q100 rating puts it in the under-hood or cabin-electronics temperature band, where a quartz oscillator's aging or shock sensitivity might drift the clock edge. Supply voltage spans 1.71V to 3.63V, so the same oscillator can serve a 1.8V MCU core clock and a 3.3V peripheral bus without a separate regulator rail.

4-VFLGA package and board integration
Housed in a 4-VFLGA measuring 1.60 mm x 1.20 mm with a seated height of 0.89 mm — the land pattern requires a 0.50 mm pitch fan-out; the small footprint leaves room for decoupling caps close to the supply pin, which matters for keeping the phase-noise floor low when the oscillator shares a rail with switching converters.
