Product details

Why choose a MEMS oscillator over quartz for automotive use

The oscillator operates from a single 1.8V to 3.3V supply, covering the common digital core and I/O rails without an external regulator. This is useful for battery-powered ECU modules that sleep between wake-up events.

The 4-SMD, no-lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm. This compact footprint matches standard 3.2 x 2.5 mm XO land patterns, making it a drop-in replacement for many quartz oscillators of the same size.

Frequently asked questions

Is DSC1001CI5-012.5000T a direct replacement for a standard 12.5 MHz quartz oscillator?

Functionally yes — it outputs a CMOS clock at 12.5 MHz with ±10 ppm stability, same as a quartz XO. The MEMS resonator gives better shock/vibration tolerance, which matters for automotive or industrial applications. Check the supply voltage range (1.8V to 3.3V) and the 4-SMD footprint to confirm it matches your existing PCB land pattern.
