Programmability for EMI reduction – up to 30 dBm lower

SiTime’s spread spectrum oscillators provide maximum flexibility by incorporating programmability in spread type, amplitude, modulation technology, output voltage swing and slew rate.

These solutions solve EMI problems without compromising performance. And, they accelerate time to revenue by ensuring emissions compliance without costly retests, problematic redesign, or expensive re-packaging.

With a variety of available features – all in one small device – designers can achieve emissions compliance, quickly and easily.
