Making it possible
TransSiP has worked on power integrity in Irvine, California since 2014. We discovered Switching Noise Jitter, patented a way to remove it, and have shipped millions of Harmony PI Filters worldwide.
About TransSiP
Every piece of digital technology has to deal with noise to work properly. For decades, the filters that remove it improved little, and engineers came to treat that limit as a fact of design. TransSiP's work started from a different question: what is the noise that the filters miss?
The answer, Switching Noise Jitter, led to the Harmony PI Filter and the Symphony DC-DC chipset. Harmony is now used in AI-data-center optics, 5G reference clocks, mission-critical radios, GNSS wearables and optical biosensors. Its results have been measured with Nokia Bell Labs, Rohde & Schwarz, MACOM, Keysight and NYU WIRELESS. To expand output capacity, TransSiP set up production with top-tier outsourced manufacturers in Japan and Thailand.
