The DSC6001HI2A-072.0000 is a 72 MHz MEMS-based XO (Standard) 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 has discontinued this order code (cite:).
Why the AEC-Q100 grade matters in a timing circuit
AEC-Q100 qualification (cite:) means this oscillator passed stress tests for temperature cycling, ESD, and latch-up immunity per the automotive IC reliability standard. The 1.71V to 3.63V supply range (cite:) covers both 1.8V and 3.3V logic rails without an external level translator, simplifying the power tree in mixed-voltage designs.
