Product details

Output is CMOS at 350 kHz, a frequency suited for low-speed reference clocks — CAN transceiver timing, LIN bus master clock, or RTC calibration — rather than high-frequency processor or SerDes links.

Supply range and stability across temperature

Operates from 1.71V to 3.63V, covering 1.8V, 2.5V, and 3.3V logic rails without a separate LDO. The wide input tolerance simplifies power-tree design when the same oscillator must work across multiple board variants. For a 350 kHz clock, this translates to a maximum frequency error of ±17.5 Hz — well within the tolerance of most UART and CAN bit-rate generators.

Enable/Disable and package footprint

Housed in a 4-VLGA package measuring 2.50mm x 2.00mm with a seated height of 0.89mm.

Product status is Active per Microchip's lifecycle designation. Sourced through independent distribution channels.

Frequently asked questions

Where can I buy DSC6003JI1B-350K000 and what is the lead time?

This part is sourced through independent distribution. Availability and lead time are confirmed at RFQ against your specific quantity. Submit a request for quote (RFQ) for current pricing and delivery commitment.

Is DSC6003JI1B-350K000 AEC-Q100 qualified?

Yes, the Ratings field lists AEC-Q100 qualification. This means the oscillator has passed the automotive-grade reliability stress tests — temperature cycling, ESD, latch-up — required for deployment in engine bay, cabin, and chassis ECUs.

Does DSC6003JI1B-350K000 have an enable/disable function?

Yes, the Function is Enable/Disable. The output can be tri-stated, reducing supply current to near zero — useful for low-power sleep modes in automotive or battery-powered designs.

What is the frequency stability of DSC6003JI1B-350K000?

Frequency stability is ±50 ppm over the -40°C to +85°C operating temperature range. For a 350 kHz clock, this is ±17.5 Hz maximum deviation — adequate for CAN, LIN, and UART bit-rate generation.
