True Circuits develops and markets a broad range of industry leading PLL, DLL and DDR PHY hard macros for ICs for the semiconductor, systems and electronics industries. TCI's robust state-of-the-art circuits, methodical and proven design strategy, and close association with the world's leading fabs, IDMs, and design services companies allow the company to quickly and reliably create new and innovative designs in a variety of advanced process technologies.
True Circuits DDR 4/3 PHY is a high-performance, scalable system using a radically new architecture that continuously and automatically adjusts each pin individually, correcting skew within byte lanes. This state-of-the-art tuning acts independently on each pin, data phase and chip select value. Read data eye and gate timing are also continuously adjusted. Automatic training is included for multi-cycle read gate timing and write leveling, write data eye timing, and internal and external (on DRAM) Vref setting. Remarkable physical flexibility allows the PHY to adapt to each customer's die floorplan and package constraints, and is delivered and verified as a single hard macro for easy timing closure with no assembly required. The PHY is also DFI 3.1 compliant, and when combined with a suitable DDR 4/3 memory controller, a complete and fully-automatic DDR 4/3 system is realized.
True Circuits' complete family of standardized and silicon-proven clock generator, general purpose, deskew, low bandwidth and spread spectrum PLLs and multi-slave and mutli-phase DDR DLLs spans nearly all performance points and features typically requested by ASIC, FPGA and SoC designers. These high quality, low jitter PLL and DLL hard macros are optimized for a wide variety of interface standards, including DDR, PCIE, SPI, HT, TDMS and HDMI. True Circuits PLLs and DLLs are available for immediate delivery in a range of frequencies, multiplication factors, sizes and functions in TSMC, GlobalFoundries, UMC and Common Platform processes from 180nm to 16nm. They are pin-programmable, highly process tolerant and reusable. They are also easy to integrate and are fully supported, so customers can reduce both design and silicon risks.
Since 1998, True Circuits has distinguished itself as the technology leader in the timing IP space, and its PLLs and DLLs are used extensively around the world in its customers' products with production volumes in the billions. When only the best will do, go with the timing experts!
