MEMS oscillator with automotive qualification
The DSC6001CI1A-020.0000 is a MEMS-based XO (standard oscillator) from Microchip's DSC60XX series, delivering a 20 MHz CMOS output with ±50 ppm frequency stability across the full -40°C to +85°C industrial temperature range.
Supply voltage flexibility and package footprint
Operating from 1.71V to 3.63V, the oscillator covers 1.8V, 2.5V, and 3.3V logic rails without an external LDO — the wide input range simplifies power-tree design and reduces BOM count. Housed in a 4-SMD, no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm, the footprint matches standard 3225 crystal oscillator land patterns — no board layout change from a quartz XO of the same size. Surface-mount assembly with the no-lead package requires standard reflow profiling; the MEMS resonator is less sensitive to mechanical shock than quartz, but the same moisture sensitivity level (MSL) bake and handling precautions apply.
Obsolete status and sourcing path
A functionally equivalent MEMS oscillator from the same DSC60XX family with the same package and supply range may serve as a drop-in, but each order code must be verified against the original timing requirements.
