52 MHz MEMS oscillator with automotive qualification
The DSC6001CI1A-052.0000T is a 52 MHz XO (Standard) from Microchip's DSC60XX series, built on a MEMS resonator rather than a quartz crystal — it delivers ±50 ppm frequency stability across the -40°C to +85°C industrial temperature range, with a typical supply current of 1.3 mA.
Obsolete — sourcing path for existing BOMs
If you are designing a new board, do not allocate this part. Look at Microchip's current DSC60XX active offerings (same 4-VDFN footprint, same 1.71V–3.63V supply range) for a pin-compatible replacement — confirm the frequency stability and temperature grade match your requirement.
The 4-VDFN package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a standard MEMS oscillator footprint that fits most 4-pin oscillator land patterns without a board spin. Supply voltage spans 1.71 V to 3.63 V, covering 1.8 V, 2.5 V, and 3.3 V logic rails without an external regulator — one BOM line serves multiple core voltages across a design family.
