The DSC6003JI2B-001.0000 is a 1 MHz MEMS-based XO (Standard) oscillator from Microchip's DSC60XX series, delivering a CMOS output with ±25 ppm frequency stability across the full -40°C to +85°C industrial temperature range.
Supply flexibility and low power draw
The wide supply range of 1.71V to 3.63V lets it run directly from a 1.8V or 3.3V rail without an extra regulator — a common need in mixed-voltage automotive ECUs. Typical supply current is just 1.3 mA, which keeps the thermal budget low in the compact 4-VLGA package (2.50mm x 2.00mm) and suits battery-backed modules that stay powered during sleep.
Enable/Disable function and package footprint
Surface-mount 4-VLGA package with a seated height of 0.89 mm fits tight vertical stacks; the 0.50 mm pitch demands careful fan-out on a 2-layer board.
