Product details

75 MHz MEMS clock for automotive and industrial boards

Rated for -40 to 85°C with ±50 ppm frequency stability and AEC-Q100 qualification, this part is designed for under-hood and engine-bay electronics where a quartz oscillator might drift or fail under vibration. The Enable/Disable function lets the system pull the output into a high-impedance state, cutting supply current from 35 mA to 22 mA for power-sensitive sleep modes.

Package and board-fit for 6-SMD no-lead

The 6-SMD no-lead package measures 2.50 mm x 2.00 mm with a seated height of 0.90 mm — a compact footprint that fits dense automotive ECU layouts where board real estate is tight. Surface-mount assembly with standard reflow profiles; no special handling beyond normal MSL precautions for a MEMS device.

Active production with AEC-Q100 traceability

Suitable for new designs and production ramp. The AEC-Q100 rating means the part has passed automotive-grade reliability stress tests (temperature cycling, ESD, latch-up) and carries PPAP documentation for tier-1 automotive supply chains.

Frequently asked questions

Does DSC1121DI1-075.0000T meet AEC-Q100 automotive qualifications?

Yes, it carries AEC-Q100 rating, covering the -40 to 85°C temperature grade and automotive reliability stress testing. Suitable for under-hood and cabin electronics where a quartz oscillator might not hold stability under vibration.

What is the difference between DSC1121 and DSC1122 series?

The DSC1121 series (this part) is a standard XO with CMOS output and Enable/Disable function. The DSC1122 series adds a spread-spectrum modulation feature to reduce EMI, but shares the same MEMS resonator core, package, and supply voltage range. For a non-spread-spectrum clock, the DSC1121 is the correct choice.
