The DSC6003CI2A-012.0000 is a MEMS-based XO (Standard) from Microchip's DSC60XX series, delivering a 12 MHz CMOS output with ±25 ppm frequency stability across the full -40°C to +85°C industrial temperature range.
For an ongoing BOM line, a cross-reference to a current-production MEMS oscillator in the same 4-SMD footprint should be evaluated.
Supply and package fit for board layout
Operates from a single 1.71V to 3.63V supply rail, covering 1.8V, 2.5V, and 3.3V logic domains without an external regulator. Housed in a 4-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a compact footprint that matches standard MEMS oscillator land patterns. Maximum supply current is 1.25 mA, making it suitable for power-sensitive automotive modules where every milliamp counts.
