Product details

Automotive-grade MEMS clock source

The DSC1001CI2-004.3000T is a 4.3 MHz MEMS-based oscillator with CMOS output, built on Microchip's DSC1001 platform. Its AEC-Q100 qualification means it passes the temperature, reliability, and PPAP requirements for automotive electronics — suitable for infotainment, ADAS sensor clocks, or body-controller timing where a quartz crystal's shock sensitivity is a concern.

Supply flexibility and standby control

The standby (power-down) function pulls the disable current down to 15 µA max — useful for battery-backed modules that need to stop the clock during sleep and wake on an external event.

Housed in a 4-SMD no-lead package measuring 3.20 mm x 2.50 mm, with a seated height of 0.90 mm. Surface-mount assembly with standard reflow profiles; no special bake-out required for the MEMS die.

Frequently asked questions

Is DSC1001CI2-004.3000T 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) and is PPAP-ready for production vehicle programs.

Can DSC1001CI2-004.3000T replace a standard 4.3 MHz quartz oscillator?

Functionally yes — it provides the same 4.3 MHz CMOS clock output with ±25 ppm stability. The MEMS resonator is inherently more shock- and vibration-tolerant than a quartz crystal, which can matter in automotive or industrial environments. Pinout and footprint match the standard 4-SMD no-lead oscillator layout, so it is a drop-in replacement on the BOM.
