Product details

16.7772 MHz MEMS XO with AEC-Q100 grade

The DSC6001JI2B-016.7772T is a MEMS-based XO (standard oscillator) from Microchip's DSC60XXB series, delivering a 16.7772 MHz CMOS output with ±25ppm frequency stability across the full -40°C to +85°C range. Rated AEC-Q100, this part is qualified for automotive applications — the MEMS resonator offers better shock and vibration tolerance than a quartz crystal, which matters for under-hood and chassis-mounted ECUs.

Supply voltage and current draw

Operates from 1.8V to 3.3V, covering the common digital core and I/O rails in automotive and industrial designs. Typical supply current is 1.3mA max, keeping the thermal budget low in a sealed enclosure.

Package and enable/disable function

Housed in a 4-VLGA package measuring 2.50mm x 2.00mm with a seated height of 0.89mm — a compact footprint for space-constrained PCBs. The enable/disable pin allows the output to be tri-stated for power savings or test modes.

Sourced through independent distribution; quoted to order against the BOM quantity. No pin-compatible second source is listed, so the BOM carries single-source risk for this exact frequency and package.

Frequently asked questions

Is DSC6001JI2B-016.7772T AEC-Q100 qualified?

Yes, the DSC6001JI2B-016.7772T carries an AEC-Q100 rating, meaning it has passed automotive-grade reliability stress tests including temperature cycling, ESD, and latch-up. This qualifies it for use in under-hood and cabin ECUs where the ambient temperature can reach 85°C.

Can DSC6001JI2B-016.7772T replace a standard quartz oscillator?

Yes, it is a drop-in replacement for a quartz XO in the same 4-VLGA footprint, provided the supply voltage and output type (CMOS) match. The MEMS resonator gives better shock resistance and faster startup than quartz, but the electrical interface is identical.
