Innovative Solutions for the emerging LAN/WAN & Broadband Markets
SOFT MIXED SIGNAL CORPORATION, is a high-technology start-up company developing and marketing system level mixed signal integrated circuits for the newly emerging high-performance LAN, WAN and serial bus markets, mainly FAST ETHERNET 100Mb/s, ATM, XDSL: ADSL/VDSL/HDSL and FIBER CHANNEL.
We are experienced in Ethernet, Fast Ethernet, Communications IC development, Mixed signal PMD development for high speed ( 100Mb/s and over ), digital system architecture and DSP for data-communications. The developments are focused in high-performance analog, DSP, networking architectures for LAN/WAN markets.
SOFT MIXED SIGNAL CORPORATION has been involved in developing specific designs to address these
markets and applications. In addition to the system expertise being developed,
the company has developed analog design methodologies, specific circuit
topologies and techniques and layout methods that enable it to utilize industry
standard digital CMOS processes to implement these designs. Traditional analog
circuit techniques generally require more expensive and special processes
(Bipolar, BiCMOS with double poly, thin film requirements) and do not lend
themselves for large-scale integration due to methodology, cost, low yields,
etc. In our design methodology we
employ fully differential topologies, self
with no additional capacitor compensation required, noise immune mixed signal topology
digital VLSI IC environment and
self-calibration for process variations. We offer these
functions in the form of technology
independent mega-cell blocks.
In addition to the above features, every
function that we develop has the complete testability provided through embedded
test structures and necessary generic test programs and algorithms. The physical
design contains necessary multiplexing, isolating, scanning, etc to
examine each particular block. The designs are also
accompanied by HDL (VHDL or Verilog) model descriptions to enable them to be
incorporated into large VLSI components or used in system level simulations for
board level designs. These models accurately describe the digital interface
functionality and somewhat less accurately the analog behavior of the function,
but provide enough information for high level functional simulations.
We have already developed the following core technologies based on pure digital CMOS process technology with 0.13um to 0.5um design:
Proprietary CMOS analog adaptive equalizers up to 155 Mb/s.
filters up to 7th order, 30Mhz employing GM and current mode continuous time.
A/D, video DAC, sigma-delta ADC/DAC.
