True Circuits, Inc. (TCI) develops and markets a broad range of Phase-Locked Loops (PLLs), Delay-Locked Loops (DLLs), and other mixed-signal designs for integrated circuits for the semiconductor, systems and electronics industries. TCI currently licenses its PLL and DLL hard macros directly to customers and receives licensing fees for the design and integration services.

TCI offers the industry's largest portfolio of standardized Phase-Locked Loop and Delay-Locked Loop hard macros available in TSMC, GLOBALFOUNDRIES and UMC logic processes from 0.18um to 16nm. Its PLLs perform clock generation, deskew, frequency synthesis, jitter filtering and spread-spectrum functions. Its DLLs delay a set of signals by precise and adjustable fractions of a reference clock cycle independent of voltage and temperature and are ideal for high-speed DDR interface applications.

True Circuits offers five general categories of low-jitter PLL hard macros: General Purpose PLLs, Clock Generator PLLs, Spread Spectrum PLLs, Low Bandwidth PLLs, and Deskew PLLs. The company also offers low-jitter Multi-slave DDR DLL and Multi-phase DLL hard macros.
