Product details

What the AEC-Q100 rating means for your automotive BOM

74.25 MHz CMOS output — where it fits

74.25 MHz is the standard pixel clock for 1080p video at 60 Hz and for many display interfaces.

The 1.8V to 3.3V supply range means the same oscillator works across a 3.3V I/O bank or a 1.8V core rail without a voltage divider.

7.00 mm x 5.00 mm, 4-SMD with no-lead exposed pad — the pad is the thermal and mechanical anchor. The 0.90 mm seated height keeps it low-profile for card-edge or mezzanine assemblies. Standard reflow profile applies; no special bake-out needed for MEMS resonators.

Frequently asked questions

Can DSC1001AI2-074.2500 replace a standard quartz oscillator in an automotive design?

Yes — the AEC-Q100 qualification means it meets the same reliability and temperature-grade requirements as automotive quartz oscillators, and the CMOS output is directly compatible. The MEMS resonator is inherently more shock- and vibration-tolerant than quartz, which is an advantage in high-vibration environments.

What is the standby function of DSC1001AI2-074.2500?

The standby (power-down) function disables the output and reduces supply current to 15 µA max, allowing the system to gate the clock during sleep without an external load switch.
