The DSC1001CI2-043.0000 is a 43 MHz XO (Standard) built on a MEMS resonator rather than a quartz crystal — the ±25 ppm frequency stability holds across the full 1.8 V to 3.3 V supply range without external load capacitors.
The DSC1001 series is Microchip's current MEMS oscillator family, so this order code remains a valid BOM line for new builds. No stock-holding claim — confirmed at RFQ.
Yes, it carries an AEC-Q100 rating, which means it has passed automotive-grade reliability stress testing (temperature cycling, ESD, latch-up) and is suitable for under-hood and cabin electronic modules.
Yes, the standby (Power Down) function disables the output and cuts supply current to 15 µA max, letting the oscillator be gated by a GPIO or a power-management controller.
