Product details

MEMS oscillator at 16.9344 MHz

The DSC1001BI2-016.9344T: This is a MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a fixed 16.9344 MHz CMOS output — the exact frequency is the primary BOM identifier, not a range or adjustable setting.

Automotive-grade qualification and supply flexibility

Rated AEC-Q100, this oscillator passes the automotive IC qualification suite — temperature cycling, ESD, and reliability stress — so it can be placed on an under-hood or chassis-domain ECU without a separate PPAP waiver. The supply voltage range spans 1.8V to 3.3V, covering both low-voltage core rails (1.8V) and standard 3.3V I/O banks without needing a secondary regulator or level translator.

Standby power-down and package footprint

Housed in a 4-SMD, No Lead package measuring 5.00mm x 3.20mm with a seated height of 0.90mm — the 0.197" x 0.126" footprint matches industry-standard 5x3.2mm oscillator pads, so a layout designed for a quartz XO of the same size accepts this MEMS part without a board spin.

Frequently asked questions

What is the exact frequency of DSC1001BI2-016.9344T?

The oscillator outputs a fixed 16.9344 MHz CMOS signal. That frequency is the BOM identifier — confirm your clock tree requires this exact value before ordering.

Is DSC1001BI2-016.9344T AEC-Q100 qualified?

Yes, it carries an AEC-Q100 rating, meaning it has passed automotive-grade reliability testing. Use it in under-hood or cabin electronics without a separate qualification step.
