Product details

The MEMS base resonator inherently resists shock and microphonics better than quartz, which matters for engine control units, ADAS cameras, and infotainment modules that see constant vibration.

Supply voltage flexibility and power-down standby

Package and mounting for automated assembly

Housed in a 4-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a standard 3.2×2.5 mm oscillator footprint that matches many quartz XO pads for drop-in replacement. Supplied on Tape & Reel for pick-and-place; the no-lead package requires a solder-paste stencil with aperture matching the pad layout in the datasheet — no via-in-pad needed.

The DSC1001 series is in volume production and suitable for new designs.

Frequently asked questions

What is the frequency stability of the DSC1001CI2-125.0000T?

This is tight enough for most microcontroller and communication clocking — Ethernet, USB, and general-purpose SoC references — without over-specifying for cost-sensitive designs.

How does the DSC1001CI2 compare to a quartz oscillator?

The DSC1001CI2 uses a MEMS resonator instead of a quartz crystal. MEMS oscillators are inherently more resistant to vibration and shock, have faster startup times, and are less susceptible to microphonics. The ±25 ppm stability matches many quartz XO grades, so it can often be a drop-in replacement in the same 3.2×2.5 mm footprint without board changes.
