Product details

Fixed 1.8432 MHz clock source with ±10 ppm stability

CMOS output and standby power-down function

The output is CMOS, which directly drives the clock input of most MCUs and SoCs without a level translator.

AEC-Q100 qualification for automotive deployment

Rated AEC-Q100, this oscillator has passed the automotive-grade temperature cycling, ESD, and reliability stress tests.

4-SMD footprint and supply voltage range

Housed in a 4-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm, the DSC1001CL5-001.8432 fits the standard 3.2 x 2.5 mm oscillator footprint used across the DSC1001 series. Supply voltage is 1.8V to 3.3V, which lets it run from a 1.8V core rail or a 3.3V I/O rail without an external regulator — the internal LDO regulates down to the MEMS core.

Frequently asked questions

What is the output type of the DSC1001CL5-001.8432?

CMOS. The output swings rail-to-rail between the supply voltage and ground, compatible with standard digital clock inputs on MCUs, FPGAs, and SoCs.

Is the DSC1001CL5-001.8432 AEC-Q100 qualified?

Yes, it carries an AEC-Q100 rating, which means it passed the automotive-grade qualification tests for temperature, reliability, and ESD. This is suitable for under-hood or cabin electronics where the ambient temperature can reach 105°C.

How does the standby function work on the DSC1001CL5-001.8432?

The standby (power-down) function disables the output and reduces the supply current to 15 µA max. When the standby pin is asserted, the oscillator stops and the output goes high-impedance. De-asserting the pin restarts the oscillation within the start-up time specified in the datasheet.
