Product details

AEC-Q100 qualified, this oscillator is suited for automotive electronics — under-hood sensor interfaces, infotainment clocking, and ADAS timing chains where quartz crystals risk failure from shock or vibration.

Supply voltage flexibility and power-down mode

Operates from any rail between 1.8V and 3.3V, covering common digital supply voltages — 1.8V for low-power SoCs, 2.5V for FPGAs, 3.3V for legacy logic — without needing a separate regulator or level translator.

Supplied in Tape & Reel (TR) in the standard 7.0mm x 5.0mm 4-SMD no lead exposed pad package.

Frequently asked questions

What is the exact frequency of DSC1001AI2-004.1943T?

The exact output frequency is 4.1943 MHz. This is a standard frequency commonly used in UART baud-rate generation and microcontroller clock trees.

Is DSC1001AI2-004.1943T AEC-Q100 qualified?

Yes, it carries AEC-Q100 ratings. This qualifies the oscillator for automotive applications, including under-hood and chassis domains where temperature extremes and vibration are present.

What is the output type of DSC1001AI2-004.1943T?

The output is CMOS. It provides a rail-to-rail square wave compatible with standard digital logic inputs — no external termination or level shifting needed for most MCU and FPGA clock inputs.
