Product details

Automotive-grade MEMS clock for in-vehicle networks

The DSC6001JI1B-033.3333T is a 33.3333 MHz MEMS-based XO (Standard) from Microchip's DSC60XXB series, qualified to AEC-Q100 for automotive applications. Its CMOS output and enable/disable function make it a direct-fit reference clock for automotive Ethernet, CAN FD, and infotainment serial buses that require a 33.3333 MHz source.

Supply flexibility and temperature coverage

Package and footprint for production

Housed in a 4-VLGA package measuring 2.50mm x 2.00mm with a seated height of 0.89mm, the DSC6001JI1B-033.3333T fits tight PCB layouts common in automotive camera modules and telematics units. The surface-mount package is supplied in Tape & Reel, compatible with standard pick-and-place lines.

Frequently asked questions

Is DSC6001JI1B-033.3333T AEC-Q100 qualified for automotive use?

Yes, the DSC6001JI1B-033.3333T carries an AEC-Q100 rating, qualifying it for automotive applications including under-hood and cabin environments within the -40°C to 85°C temperature range. This means it has passed the reliability stress tests and PPAP requirements for automotive ICs.

What is the frequency stability of DSC6001JI1B-033.3333T?

The frequency stability is ±50 ppm. For a 33.3333 MHz carrier, this translates to a maximum frequency deviation of ±1.67 kHz across the operating temperature and supply range — sufficient for most automotive serial bus reference clocks, though precision Ethernet PHY applications may require tighter stability.

Can DSC6001JI1B-033.3333T be used with a 1.8V supply?

Yes, the supply voltage range is 1.8V to 3.3V, so a 1.8V rail is within specification. The CMOS output swing scales with the supply voltage — at 1.8V, the output high level is approximately 1.8V, which is compatible with 1.8V logic inputs.

How does DSC6001JI1B-033.3333T compare to other MEMS oscillators like SiT8003?

The DSC6001JI1B-033.3333T is AEC-Q100 qualified, which the SiT8003 typically is not — that is the primary differentiator for automotive BOMs. Both offer similar frequency stability (±50 ppm) and supply ranges, but the DSC6001JI1B-033.3333T carries the automotive-grade reliability documentation required for PPAP submission.
