Atheros
Communications, Inc., announced the company’s first cellular solution, the
Atheros AR1900. In a single chip, the AR1900 implements a complete cellular
transceiver, baseband, application processor, audio paths, power management, and
keypad, display and USB interfaces. Through this high level of integration
coupled with the addition of new industry leading features, the AR1900 enables
industry-leading performance at a price that is designed to fuel further market
growth. The AR1900 is the first product to leverage a platform of innovative
technologies developed by Atheros over the last year, including audio, voice,
low-power battery operation and novel RF architectures.
The
AR1900 is the world’s first single-chip solution for PHS (Personal Handyphone
System), which is widely deployed in China, Japan, Taiwan and other countries.
PHS, or Personal Access System (PAS) as it is known in China, is an advanced
digital TDMA-TDD technology operating at 1.9 GHz providing high-quality voice,
advanced data services, and long battery life. The growth of PHS in China has
been driven by its favorable infrastructure cost and voice tariff structure,
which is less than half that of other cellular technologies.
“PHS
has experienced remarkable growth in China since its introduction in the late
1990’s and accounted for almost 20% of the cellular market in 2004 or over 68
million subscribers,” said Will Strauss, president of Forward Concepts. “We
anticipate the market to continue its strong growth trend and expect low-cost,
high-performance solutions, such as that offered by Atheros, to further fuel
adoption.”
“We
have expanded our core competencies to include audio, voice and power
management,” said Craig Barratt, president and chief executive officer of
Atheros Communications. “We can now deliver solutions for broader handheld and
voice markets, with PHS as the first target. These capabilities, combined with
our world-class digital CMOS Radio-on-a-Chip (RoC) expertise, enable us to bring
to market the most highly integrated, low power, and cost-effective wireless
solutions – within the shortest design cycle.
The
AR1900 integrates a complete handset solution, including 1.9 GHz transceiver,
baseband, protocol control block, application processor, voice coder and analog
paths, polyphonic ring-tone generator, power management, and LCD, keypad and USB
interfaces, into a single piece of silicon. It is implemented in a standard
digital CMOS process; the innovative single-chip design reduces the cost of PHS
handsets by 30 percent compared to multiple chip solutions.
The AR1900 boasts several technology innovations
for PHS. Its state-of-the-art fractional-N synthesizer allows for seamless
handover between base stations. It supports the PIAFS mode of operation, which
allows for data transfer at 64 kbps. The AR1900 also supports connection to up
to three other PHS devices, allowing it to be used for indoor infrastructure
equipment. It implements aggressive clock gating and other power reduction
features to maximize battery life.
The AR1900 is the
latest in a string of Atheros accomplishments in single-chip integration
achieved through its RoC methodology. Atheros introduced the world's first
single-chip 802.11g client solution in January 2004, the world's first
single-chip 802.11a/b/g client solution in October 2004, and the world's first
single-chip 802.11g access point solution in December 2004. The AR1900 brings
Atheros advantages in system performance, cost and integration, and power
consumption to the cellular market.
