Technology Brief
Energy, vitality, know-how, and creativity have brought advances that make AKM a leader in key communications
and multimedia IC technologies. AKM is a world leader in two key technologies for communications and multimedia
applications: mixed-signal multimedia and ASSP DSP. This is accomplished through early perception of the technological
needs at the leading edge and rapid development of systems of high added value that effectively anticipate these
requirements. Development work is unrestrained by conventional methods or boundaries. AKM seeks and works
closely in technological alliance with leading experts and organizations at home and abroad. Its engineers participate
globally in leading scientific and technological symposia. It incorporates the most advanced process and development
equipment and systems available, from around the world, to provide IC’s that meet the emerging needs. It is a
corporation focused on the future, and united in its purpose.
The key to AKM’s success is the conceptualization, know-how, and innovation emerging from the stimulus and
synthesis of knowledge and experience in many fields. The Asahi Kasei Group, with fields of business ranging from
basic chemicals to pharmaceuticals and from polymers and apparel to luxury homes, is recognized in each field for
its distinctive approach to business and operations and its tradition of original research, development, and innovation
often leading to concepts and technologies that overturn the parameters of conventional wisdom. AKM, since its
inception, stands out even among the members of this group, for bold planning and flexible operation that break the
conventional mold, and for its strength in high-level technologies and their synthesis.

function peripherals meet a wide range of high-precision, high-resolution image processing needs. The lineup also
includes video ADCs for high-pixel-count CCDs, ADCs for high-speed signal conversion, and ICs with NTSC/PAL
signal processing inputs and outputs. AKM’s cutting-edge image processing ICs are expanding the possibilities for
development of new, high performance multimedia equipment.
• Analog front-ends for FAX, MFP, scanners, copiers • SD and HD video encoders
• NTSC/PAL decoders and encoders • SD and HD video filters and drivers
Crystal Oscillator IC’s
Main clock modules of digital cellular and digital cordless phones conventionally require several discrete parts, including
a thermistor as a temperature sensor, and a variable diode as an oscillator. Analog Temperature Compensated Crystal
Oscillator (TCXO) ICs from AKM provide a compact, 1-chip solution that meets the need for clock modules, as portable
handsets become progressively smaller.
Touchscreen Controllers
AKM offers a complete family of touchscreen controllers, including devices with integrated audio converters. Flexible
control interfaces include both SPI format and I2C format. Designed for portable products, AKM touchscreen controllers
offer very low power consumption in small packages, ranging down to 3mm X 4mm. Some products feature industry
standard pinouts and specifications for fast time-to-market.

Video Products
AKM now offers data data conversion circuits for digital video applications. By focusing on the needs
of mobile video applications, AKM consistently designs products that meet the specific requirements
for handheld video devices. AKM mobile video products primarily use composite video only, requiring
a single data conversion circuit. Unlike traditional video encoders and decoders that use two or three
converter circuits, AKM’s single converter architecture holds down cost, power, and size. Offering both
encoders and decoders that need less than 100mW of power extends battery life for mobile products.
NTSC/PAL decoder and encoder applications:
• Multimedia-enabled mobile phones • Portable video recorders
• Portable media players • Remote security cameras
• Wireless media players • Video capture cards

Video Amplifiers
In addition to converters, AKM has video amplifiers
for space and cost-sensitive applications. A
charge pump is used to create a negative rail for
the amplifier, so when operating off of a single
+3V power supply, the video output is ground -
referenced, and the output can be direct coupled
to the jack. The charge pump makes it easy to
eliminate the traditional large and expensive
coupling capacitors found in video outputs. The
product family saves further space by fixing the
gain, eliminating gain-setting pins and feedback
networks.

Mixed-Signal
Although AKM is most well known for our premier digital audio converter products, we are about much
more than just audio. We also use our advanced mixed-signal process technology to design products
for applications including mobile communications, optical networking, telecom, and data storage.
Our products offer diverse functions such as laser diode drivers for networking and optical storage
applications, analog baseband, PLL’s and RF for CDMA handsets, transceivers for telecom equipment,
and PCM CODEC’s for telecom CPE. We also take advantage of our analog design experience to create
innovative products such as the electronic compass detailed on this page.

-Axis Electronic Compass
GPS-enabled navigation systems are becoming quite common. One of the drawbacks with these systems
is the user’s perception of the map direction. Most maps are drawn with north at the top of the map.
If the user is oriented in a different direction, they can become confused. The most useful navigation
system re-orients the map in the user’s direction, possible with an electronic compass.

Clock Generators
AKM is now utilizing its outstanding analog PLL technology for clock generators and other clocking
devices. Known for its extremely low jitter, the PLL’s offer unparalleled performance in products such as
single clock generators, multi-clock generators (fan-out), spread spectrum clock devices, and zero delay
buffers. In addition to the low jitter characteristics, these products offer very low power consumption,
low voltage operation, and small package sizes.
Single Clock Generators
The family of single clock generators allow for selection between two output frequencies. These devices
are PLL-based, and they offer outstanding jitter performance. The package is a 6-pin SON.
