The DSC1001DI1-001.8432T is a Microchip MEMS-based XO (standard oscillator) delivering a 1.8432 MHz CMOS output with ±50 ppm frequency stability across the full -40 to +85°C industrial/automotive temperature range.
Operates from a single 1.8V to 3.3V supply rail, simplifying BOM consolidation across multi-voltage designs — the same part can serve a 1.8V MCU core or a 3.3V peripheral bus.
Yes, it carries AEC-Q100 ratings, meaning it passed automotive-grade reliability stress tests including temperature cycling and ESD immunity — suitable for under-hood and cabin applications.
Stability is ±50 ppm over the full -40 to +85°C range, which is tight enough for most UART, SPI, and general-purpose clocking — no external trimming required.
Functionally yes — it provides the same CMOS clock output at 1.8432 MHz. The MEMS base is more shock-tolerant and does not need load capacitors, but confirm the pinout and footprint match your existing quartz oscillator's 4-SMD layout.
