The DSC6003MI2B-080.0000 is an 80 MHz MEMS-based oscillator from Microchip's DSC60XXB series, delivering a standard CMOS output with ±25 ppm frequency stability across the full -40°C to +85°C range. Supply voltage spans 1.71V to 3.63V, so it can run from a 1.8V, 2.5V, or 3.3V rail without a separate regulator — one less part on the BOM.
Housed in a 4-VFLGA package measuring 2.00 mm x 1.60 mm with a seated height of 0.89 mm — a compact footprint that fits tight layout constraints on multi-layer boards.
No official successor or second-source listed; the DSC60XXB series is the active family for this frequency and grade.
