The DSC6001MI2A-022.0000T is a 22 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.
Microchip lists this exact order code as Obsolete.
Package and supply — board-fit checklist
Housed in a 4-VFLGA package measuring 2.00 mm x 1.60 mm with a seated height of 0.89 mm. That's a small land-grid array — hand-soldering is possible with a fine-tip iron and flux, but a hot-air station or reflow profile is cleaner. The 0.50 mm pitch is typical for this class; a stencil with 0.25 mm apertures works for prototype runs. Supply voltage range is 1.71V to 3.63V, covering 1.8V, 2.5V, and 3.3V logic rails without an external regulator. Typical current draw is 1.3 mA — low enough for always-on clocking in a sensor node or ECU.
