Product details

Automotive-grade MEMS timing for constrained boards

The DSC1001CI2-004.0000 is a 4 MHz MEMS-based XO with CMOS output, rated AEC-Q100 — the first oscillator qualification that lets you drop it into an engine-bay ECU or a cabin-domain controller without a separate quartz can and its associated shock sensitivity. Frequency stability is held to ±25 ppm across temperature and voltage, tight enough for a CAN-FD node or a 100BASE-T1 PHY reference without external trimming.

Standby power-down for battery-conscious designs

The 4-SMD, no-lead package (3.20 mm × 2.50 mm footprint, 0.90 mm seated height) fits tight layout zones under a shield can or alongside a BGA memory device.

Product status is Active.

Frequently asked questions

Is DSC1001CI2-004.0000 AEC-Q100 qualified?

Yes — the Ratings field explicitly lists AEC-Q100. This qualifies the oscillator for automotive-grade reliability testing including temperature cycling, ESD, and latch-up, making it suitable for under-hood and cabin applications.

What supply voltage does DSC1001CI2-004.0000 accept?

The operating supply range is 1.8V to 3.3V. A single BOM line covers both 1.8V and 3.3V logic rails without a separate voltage-divider or LDO for the oscillator.

What is the output type of DSC1001CI2-004.0000?

CMOS output. The 4 MHz square wave drives standard digital inputs — MCU clock pins, PHY reference inputs, or FPGA global clock buffers — without an external level translator.

What is the closest pin-compatible alternative in the DSC1001 family?

The DSC1001 series shares the same 4-SMD no-lead footprint and pinout across all frequency variants. A different frequency within the series — for example DSC1001CI2-008.0000 for 8 MHz — is a direct drop-in replacement at the board level, requiring only a firmware clock-tree change.
