AUSTIN, Texas, June 3, 2013 -- 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 introduction of a new
high performance DDR 4/3 PHY with state-of-the-art tuning and training, and
remarkable physical flexibility to adapt to each customer's die floorplan
and package. The DDR 4/3 PHY has been developed using the powerful custom
design automation tools that have made TCI's line of high performance PLLs
and DLLs a staple in the semiconductor industry for over 15 years. The
availability of this revolutionary PHY means customers can now license a
hard PHY with significant performance and features without all the
implementation and timing closure hassles that are common with current DDR
The 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.
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.
"TCI has been providing high-performance PLL and DLL IP for a range of DDR
applications since the early days of DDR. In working closely with our
customers, it became clear to us that DDR is really a timing problem, one
that requires a deep understanding of analog timing circuits, parallel
interfaces and signal integrity", remarked Stephen Maneatis, True Circuits',
CEO. "After seeing so many customers struggle with the challenges of higher
speeds, integration complexity and timing closure, we decided to apply our
over 15 years of experience in high performance analog timing IP, and design
an entirely new DDR 4/3 PHY that addresses these challenges in a broad and
comprehensive way. The result of this effort is a hard PHY that adjusts
timing automatically to optimize performance, and is also easy to integrate
and test. Customers have always been able to count on True Circuits timing
IP for functionality, performance and quality, and they should expect
nothing less from our new DDR 4/3 PHY IP."
Availability and Licensing
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. Interested customers can

About True Circuits Attendance at DAC
At the Design Automation Conference (DAC), True Circuits will feature its
complete line of high performance and general purpose timing IP, as well as
its revolutionary new DDR 4/3 PHY IP. Brian Gardner, True Circuits' V.P. of
Business Development, will also make presentations about True Circuits and
our new DDR PHY IP in the ChipEstimate.com booth #2446 and the TSMC OIP
booth #1746 each day of the conference.

About True Circuits PLLs and DLLs
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 are available in a range of frequencies, multiplication
factors (1-4096), sizes 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 delay a set of signals
by precise and adjustable fractions of a reference clock cycle independent
of voltage and temperature, are ideal for high-speed DDR interface
applications and are available in different sizes and form factors.
Customized PLL and DLL solutions are also available for specialized chip
True Circuits PLLs and DLLs are available for immediate customer delivery in
TSMC, GlobalFoundries, UMC and Common Platform processes from 180nm to 20nm.
