Product details

Supply voltage spans 2.25V to 3.63V, so it runs from a 2.5V or 3.3V rail without an external LDO.

MEMS resonator vs quartz – reflow and reliability

It also eliminates the quartz start-up time; the MEMS resonator is ready within microseconds of power-up. The 6-SMD, No Lead Exposed Pad package (7.00mm x 5.00mm, 0.90mm seated height) is a standard footprint that places well on a standard reflow profile. Check the MSL before you place it – the MEMS die is sealed, but the package moisture sensitivity still governs bake requirements.

Frequently asked questions

Is the DSC1123AI2-090.0000 AEC-Q100 qualified?

Yes, the DSC1123AI2-090.0000 is rated AEC-Q100, which means it has passed automotive-grade stress tests including temperature cycling, ESD, and latch-up.

Can I use the DSC1123AI2-090.0000 as a replacement for a quartz oscillator?

Yes, the DSC1123AI2-090.0000 is a drop-in functional replacement for a 90 MHz LVDS quartz oscillator in the same 7.00mm x 5.00mm 6-SMD footprint. The MEMS resonator offers better shock/vibration tolerance and faster start-up, but verify the supply voltage range (2.25V to 3.63V) and the Enable/Disable logic polarity match your existing design.
