True Circuits 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.

The company was founded in 1998 by Dr. John G. Maneatis, world renowned for his innovative PLL designs. TCI built its reputation on providing quality full-custom PLLs, DLLs, and other mixed-signal designs to the world's most demanding customers. TCI continues to provide this custom service to those who require it.

To help customers with less specialized needs reduce costs and turnaround time, TCI now offers a large family of standardized PLL and DLL hard macros that spans nearly all performance points and features typically requested by ASIC, FPGA, and SoC customers. These hard macros are available for immediate delivery in a range of frequencies, multiplication factors, sizes and functions in TSMC, UMC, GLOBALFOUNDRIES and Common Platform logic processes from 0.25um to 28nm.

For customers with more specialized needs, TCI's advanced characterization and porting technology, as well as our robust state-of-the-art circuits and proven design methodology allow us to provide our customers with leading-edge PLL and DLL hard macros in a variety of process technologies quickly and reliably. The licensing terms for our standardized and custom hard macros do not involve royalty payments.

TCI's reputation for reliability and timing excellence is unmatched. TCI's PLL and DLL jitter performance is among the best in the industry. Its leading-edge designs are both versatile and highly process tolerant. The entire business model and product line have been specifically designed so customers can license premium quality PLLs quickly and easily with the highest confidence that their chip design will work on the first silicon.

This website exists to answer your questions about PLLs and DLLs, and to help you determine if your needs can be met by one of TCI's standard hard macros. If you do not see a hard macro that meets your specifications, TCI will be more than happy to discuss a customized solution with you.
