Product details

The DSC1001AI2-040.0000T is a 40 MHz MEMS-based XO (Standard) producing a CMOS output. AEC-Q100 qualification confirms this part is screened for automotive-grade reliability: temperature cycling, ESD, and latch-up testing per the automotive IC stress standard. It belongs in an engine-control module, a transmission controller, or an ADAS sensor hub where a quartz failure would strand the vehicle.

The 1.8V to 3.3V supply range lets this oscillator drop into a 1.8V-core FPGA bank, a 3.3V MCU, or a 2.5V SerDes reference without a dedicated regulator — the internal LDO in the MEMS die handles the rail variation.

Housed in a 4-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm, the DSC1001AI2-040.0000T uses a standard oscillator footprint shared by many quartz and MEMS XOs.
