Product details

MEMS-based XO for frequency-flexible designs

The DSC8121AI2: It is supplied as a blank device (User Must Program), meaning the output frequency is set during board-level programming rather than at the factory — a workflow suited to designs that stock one base part number and configure it per BOM position.

Sourcing and lifecycle posture

As a programmable MEMS oscillator, it offers a single SKU that can be configured to any frequency in the 10-170 MHz range — a logistics advantage for BOM consolidation when multiple clock frequencies are needed across a product family.

Frequently asked questions

What is the DSC8121AI2's output type and frequency range?

It outputs a standard CMOS signal and covers a programmable frequency range of 10 MHz to 170 MHz.
