Its 1.8V to 3.3V supply range lets it run from the same rail as a 1.8V MCU or a 3.3V SoC without a level translator.
Housed in a 4-SMD, No Lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm. The 0.197" x 0.126" footprint is common across many 4-pin oscillators — the land pattern matches the standard 4-pad ceramic oscillator layout, so a PCB designed for a quartz XO can often take this MEMS part without a board spin.
The DSC1001 series is a current production line from Microchip.
