True Circuits, Inc.

Provider of PLL and DLL hard macros


True Circuits develops and markets a broad range of Phase-Locked Loops (PLLs), Delay-Locked Loops (DLLs), DDR PHYs, and other mixed-signal designs as hard macros.

The company’s PLLs perform clock generation, deskew, frequency synthesis, jitter filtering and spread-spectrum functions. The 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. Hard macros are available  in a range of frequencies, multiplication factors, sizes and functions in TSMC, GlobalFoundries, and UMC logic processes.
