True Circuits Announces New Line of PLLs, the "Ultra PLL", that offers exceptional performance, features and ease of use

Los Altos, California, April 6, 2015 -- True Circuits, Inc. (TCI), a leading provider of analog and mixed-signal intellectual property (IP) for the semiconductor, systems and electronics industries announced today the availability of a new line of Phase-Locked Loop (PLL) hard macros that is well suited for the most demanding chip applications, including high-speed SerDes and ADC input clocks. The “Ultra PLL” is designed as an ultra low jitter, extremely wide range clock multiplier with precise fractional frequency control and optional spread spectrum capability, giving chip designers the ultimate in performance, features and ease of use. It is available in a variety of TSMC, GLOBALFOUNDRIES and UMC processes.

The Ultra PLL employs a new state-of-the-art architecture and uses high-speed digital and analog circuits to achieve exceptional performance, with many useful features. It has ultra low jitter (<500fs) for the most demanding SerDes and ADC input clocks. It has ultra wide frequency range with multiplication factors from 3 to over 250,000, supporting reference clocks as low as 32KHz. It also has precise frequency control with a least 26 fractional bits (at least 10 precise) for extremely high fractional-N resolution. It can even generate precise and adjustable frequency spreading with programmable rate and depth to meet tight FCC requirements. The Ultra PLL packs all these features into a compact size that draws low power and, with full pin programmability, one PLL can be used for all applications on a SoC.

“The growing complexity of today’s SoCs and FPGAs presents chip designers with ever increasing challenges that often result in compromises on features, performance and flexibility”, remarked John Maneatis, Ph.D., True Circuits, President. “Our goal is to help chip designers tackle these challenges with a single PLL that offers broad functionality and performance in an easy to use programmable hard macro. Whether the need is ultra low jitter for a SerDes, precise frequency resolution for HDMI or extremely low phase noise for an ADC, our new state-of-the-art Ultra PLL has them covered.”

Price and Availability

True Circuits Ultra PLLs will be available in TSMC, GLOBALFOUNDRIES and UMC processes from 65nm to 16nm. Front-end views will be ready for delivery in the month of May, with tapeout ready GDSII to follow shortly thereafter. Customers can license TCI timing IP either directly from TCI or through its global network of design services partners and sales reps. The hard macros are available for a per use license fee and no royalty fees. The license fee includes integration support from TCI and its partners to ensure a successful customer tape out. The deliverables include GDSII and LVS Spice netlists, behavioral and synthesis models, Library Exchange Format (LEF) files and extensive user documentation.

About True Circuits PLLs and DLLs

In addition to the new Ultra PLL, True Circuits offers a complete family of standardized and silicon-proven general purpose, clock generator, deskew, and spread spectrum PLLs and DDR DLLs that 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 suited to a wide variety of interface standards and chip applications. 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.

True Circuits PLLs support a wide range of frequencies, multiplication factors and functions over which they deliver optimal performance, avoiding the cost and complexity of licensing multiple point-solution PLLs from foundries or other vendors. TCI's DLLs are available in mutli-slave and multi-phase versions and different sizes and form factors. They 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 and ONFI interface applications. Customized PLL and DLL solutions are also available for specialized chip applications.

True Circuits PLLs and DLLs are available for immediate customer delivery in TSMC, GLOBALFOUNDRIES and UMC processes from 180nm to 16nm. For more information about True Circuits IP products, visit www.truecircuits.com/tci_technology.html and www.truecircuits.com/product_matrix.html.

About True Circuits DDR PHYs

True Circuits also offers a high performance DDR 4/3 PHY that 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.

The PHY employs a localized, clock deskewed PHY-to-memory controller interface to ease timing closure. The circuitry in each pin is able to measure the data eye and jitter, and calculate flight delays. The PHY also includes a full speed read/write BIST, which tests the complete read and write paths of every pin simultaneously with pseudo-random data.

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.

The True Circuits DDR 4/3 PHY is initially available for customer delivery in TSMC's 28nm HPM process. The PHY will be available in additional TSMC and GLOBALFOUNDRIES processes in the very near future.
