Product details

The DSC1001AI2-038.8800T is a MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a 38.88 MHz CMOS output with ±25 ppm frequency stability. Its AEC-Q100 qualification confirms suitability for automotive-grade applications — the part is screened to the temperature, reliability, and PPAP requirements of the automotive supply chain. The wide supply range lets it share a rail with 1.8V or 3.3V logic without an extra regulator — a clean fit for multi-voltage ECU and telematics boards.

Standby power-down and current draw

Housed in a 4-SMD, No Lead Exposed Pad package measuring 7.00 mm × 5.00 mm with a seated height of 0.90 mm. The 0.90 mm height fits within the 1.0 mm clearance typical of automotive ECU enclosures.

Frequently asked questions

Is the DSC1001AI2-038.8800T AEC-Q100 qualified?

Yes, the DSC1001AI2-038.8800T carries AEC-Q100 qualification, which means it has passed the automotive-grade reliability stress tests (temperature cycling, ESD, latch-up) and is PPAP-ready for production vehicle programs.

What is the standby current of the DSC1001AI2 when the power-down function is active?

When the standby (power-down) function is asserted, the maximum supply current is 15 µA. This low quiescent draw suits battery-backed or wake-on-event designs.
