The DSC6003JI1B-020.0000T is a MEMS-based XO (Standard) from Microchip's DSC60XXB series, delivering a 20 MHz CMOS output with ±50 ppm frequency stability across the full -40°C to +85°C temperature range.
Low power and small footprint for space-constrained boards
Typical current draw is 1.3 mA max — a fraction of what a quartz oscillator of the same frequency pulls, which matters in battery-backed or thermally tight enclosures where every milliwatt counts. The 4-VLGA package measures 2.50 mm x 2.00 mm with a seated height of 0.89 mm, fitting under low-profile shields or in multi-layer stack-ups where board real estate is at a premium.
