Product details

Automotive-grade MEMS timing for serial buses

The DSC1001CE2-001.8432T is a MEMS-based XO (Standard) oscillator from Microchip's DSC1001 series, delivering a fixed 1.8432 MHz CMOS output with ±25 ppm frequency stability. Its AEC-Q100 qualification places it in the automotive temperature grade, suitable for under-hood and chassis-domain applications where quartz oscillators would require additional screening. The 1.8432 MHz frequency is a classic baud-rate generator for UART and CAN serial interfaces, so this part fits directly into existing 1.8432 MHz clock trees without a PLL.

The supply voltage range of 1.8V to 3.3V covers the common 1.8V, 2.5V, and 3.3V rails found in automotive ECUs and industrial controllers, eliminating the need for a dedicated LDO for the oscillator.

Frequently asked questions

Is the DSC1001CE2-001.8432T a direct drop-in replacement for a quartz crystal oscillator at 1.8432 MHz?

Yes, in most designs. The DSC1001CE2-001.8432T is a MEMS-based XO with CMOS output and a standard 4-SMD, No Lead footprint — the same footprint as many quartz oscillators. The supply voltage range (1.8V to 3.3V) and ±25 ppm stability match or exceed typical quartz oscillator specs. The key difference is the MEMS resonator's higher shock and vibration tolerance, which is why it carries AEC-Q100 qualification. Verify the output drive strength and load capacitance in your specific circuit, but the pinout and electrical interface are directly compatible.
