Product details

The DSC6101MA3B-016.6666: Rated AEC-Q100, it spans -40°C to 125°C, so it handles under-hood engine-bay temps and industrial enclosures without a fan.

Supply and power budget for the BOM

Typical current draw is 3 mA, which is low enough that a small coin-cell-backed RTC circuit can keep it running during sleep. In a battery-powered ECU, this saves the 3 mA quiescent draw when the processor is in deep sleep.

Sourcing and compliance

That certification is the green light for production builds in automotive ECUs, ADAS modules, and telematics units.

Frequently asked questions

What is the output type and frequency of the DSC6101MA3B-016.6666?

It is a standard XO with CMOS output at 16.6666 MHz. The CMOS logic level swings rail-to-rail between the supply voltage (1.71V to 3.63V), so it drives most MCU and FPGA clock inputs directly.
