Who
True Circuits, Inc. (TCI), a leading provider of analog and mixed-signal
intellectual property (IP) for the semiconductor, systems and electronics
industries and member of the TSMC IP Alliance since 2004.
What
True Circuits will showcase its IoT PLLs that are specifically tailored to
the stringent power requirements and wide frequency operation range of the
rapidly-growing IoT market. Sipping only 45uW at 30MHz and running from
core power, the IoT PLL is designed for very low power. With multiplication
factors up to 8192, the PLL is able to run off of a small and inexpensive
32KHz crystal and still clock a 32-bit CPU at up to 250MHz. The IoT PLL is
ideal for applications like wearables and senor devices, where the
power-performance profile must be managed tightly, and possibly over a very
wide frequency range.
True Circuits will also showcase its high-performance Ultra PLLs that are
well suited for the most demanding chip applications, including high-speed
SerDes and ADC input clocks. The Ultra PLL employs a 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.
True Circuits will also feature its complete line of standardized and
silicon-proven general purpose, clock generator, deskew, and spread spectrum
PLLs, and multi-slave and multi-phase DLLs that spans nearly all performance
points, features and foundry processes 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, reusable and available for
delivery in TSMC processes from 180nm to 7nm, including most half nodes.
Brian Gardner, True Circuits' V.P. of Business Development, will make an OIP
presentation titled "Overcoming Timing Closure Issues in Wide Interface DDR,
HBM and ONFI Subsystems". In wide chip interfaces like DDR, HBM and ONFI,
it can be challenging to synthesize and connect high-frequency controllers
to the PHY hard macros. Clock trees can be expansive, pushing tools to
their limits, and often multiple clock domains are needed. Jitter can also
be an issue on long paths. Brian will show how True Circuits PLL and DLL IP
is being used by multiple customers to build ONFI and HBM subsystems in
advanced TSMC process nodes, and discuss the tradeoffs and timing budget
concerns among different timing architectures. In addition, he will explain
how source-synchronous signaling is used in our DDR PHY to ease timing
closure, and to allow the memory controller to be synthesized for
high-frequency operation, which reduces its size and lowers its latency. By
using a soft IP "shim" between the memory controller and PHY, the memory
controller only needs a single localized clock tree, reducing mismatch and
jitter. The long routes between the soft shim and the PHY hard macros are
source-synchronous, so data/strobe groups need only be roughly matched,
something easily accomplished by place and route tools.
