The DSC1001DI2-020.0000T is a 20 MHz MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a CMOS output with ±25 ppm frequency stability across -40°C to 85°C. The 1.8V to 3.3V supply range lets it drop into 2.5V or 3.3V clock trees without a separate regulator; the 6.3 mA max supply current keeps the thermal budget low in dense PCB layouts.
Housed in a 4-SMD no-lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm, the footprint matches standard 2.5 x 2.0 mm XO land patterns — no via-in-pad required, and the small outline suits space-constrained ECU or sensor modules.
