The DSC1001CI1-018.4320T is a MEMS-based XO (standard) from Microchip's DSC1001 series, delivering a 18.432 MHz CMOS output across a 1.8V to 3.3V supply range.
The 1.8V–3.3V supply range lets this oscillator serve multiple voltage domains without a separate regulator — a single BOM line covers 1.8V, 2.5V, or 3.3V rails.
Buyers need to find a reliable distributor with stock to source the part quickly.
Price comparison drives purchasing decisions, especially for BOM optimization.
Engineers and buyers need alternatives if the part is unavailable or for second sourcing.
Automotive buyers require AEC-Q100 certification for reliability in automotive applications.
Design engineers must verify voltage compatibility with the rest of the circuit.
Immediate availability is critical for production schedules and repair lead times.
