Product details

It operates from a 1.8V to 3.3V supply rail, drawing a maximum of 6.3 mA, and drops to 15 µA in standby mode.

What the AEC-Q100 rating means for fit

Supply voltage and output compatibility

With a supply range of 1.8V to 3.3V, this oscillator can be powered directly from a 1.8V core rail, a 2.5V I/O rail, or a 3.3V peripheral rail without an intermediate LDO. The 1.8432 MHz frequency is a common baud-rate base for UART and CAN controllers, and the ±25 ppm stability keeps the bit timing within tolerance over temperature.

For an automotive module that wakes periodically on a CAN message, the oscillator's standby current adds negligible drain to the battery-backed sleep budget.

Frequently asked questions

Is the DSC1001DI2-001.8432T qualified for automotive applications?

Yes, it is AEC-Q100 qualified.

What is the output type of the DSC1001DI2-001.8432T?

The output is CMOS, rail-to-rail swing, which directly drives the clock input of most MCUs, FPGAs, and communication controllers without level translation.

What is the frequency tolerance of the DSC1001DI2-001.8432T?

This is sufficient for CAN, UART, and most industrial communication protocols.
