MEMS oscillator at 18.1 MHz – what it replaces on the BOM
Supply range and standby – sizing the power rail
The supply voltage range spans 1.8 V to 3.3 V, covering the three most common digital logic rails without needing a separate regulator — one oscillator serves a 1.8 V MCU core and a 3.3 V peripheral bus on the same design.
Temperature grade and automotive qualification
Package and footprint – board-level fit
Housed in a 4-SMD, No Lead package measuring 2.50 mm × 2.00 mm with a seated height of 0.90 mm, the DSC1001DE1-018.1000T fits into compact PCB layouts — the small footprint is a direct replacement for standard 2.5×2.0 mm crystal oscillator packages, so a layout designed for a quartz XO can often accept this MEMS part without a board spin.
