MEMS oscillator at 439 kHz for automotive timing
The DSC6001JI3B-439K000T: This is a MEMS-based XO (standard oscillator) from Microchip's DSC60XXB series, delivering a fixed 439 kHz CMOS output with enable/disable control. Rated for -40°C to 85°C operation and AEC-Q100 qualified, it suits under-hood and cabin electronics where quartz oscillators might drift under vibration. Supply voltage spans 1.8V to 3.3V, covering common logic rails without a separate regulator.
Housed in a 4-VLGA package measuring 2.50 mm x 2.00 mm with a seated height of 0.89 mm — a compact footprint for space-constrained PCBs.
