The DSC6001MI3B-004.0960T is a 4.096 MHz MEMS-based XO from Microchip's DSC60XX series, delivering a CMOS output across a 1.71V to 3.63V supply range — one oscillator serves 1.8V, 2.5V, and 3.3V logic rails without a level translator.
Housed in a 4-VFLGA package measuring 2.00 mm x 1.60 mm with a seated height of 0.89 mm, this oscillator fits dense PCB layouts where every mm² counts — the 0.50 mm pitch LGA pads require a solder-mask-defined pad and a clean via-in-pad strategy if routing under the package. Surface-mount assembly on standard FR-4; the small package means the decoupling cap (100 nF X7R recommended) must sit within 1 mm of the supply pin to keep the supply impedance low at the MEMS drive frequency.
The DSC60XX family is in volume production, so the BOM line is not at risk of a sudden last-time-buy.
