SAMSUNG Electronics Develops ADSL Core Chipsets

SEOUL, Korea - Jan 11, 2002 - Samsung Electronics has developed all the technology required for core chipsets used in ADSL networks -- the Discrete Multitone(DMT) Processor IC, controller IC and Analog Front End (AFE) IC for use in digital modems with transmission speeds of up to 8Mbps.

Most ADSL devices on the market are fabricated with the 0.25-micron technology and operate on 2.5 volts, while Samsung has applied 0.18-micron CMOS processing that allows the company's new products to perform on just 1.8 volts. This means a 30% reduction in power consumption.

Currently, there is no company, which supplies all three core components for the ADSL modem.
Providing the core ADSL chipsets, Samsung is in a position to offer the full lineup in a bundle business required by end users to configure optimal ADSL networks. As such, the company enjoys a competitive advantage in the marketplace.

Samsung is technologically self-sufficient and did not have to rely on outside help in such areas as software and hardware in the development of its new products. Company officials say that they now have laid the groundwork for making major inroads into overseas telecommunications chipset markets, which are still in the early stages of formation.

The new chipsets will boost Samsung's system-on-a-chip (SOC) business, which is emerging as a next-generation, value-added market. In addition to offering the three core ADSL components in a chipsets package, Samsung plans to produce a DMT Processor IC and controller IC on a single chip and apply the 0.13-micron technology in the second half of 2002.

The ADSL modem market is estimated at around 10 million units this year and is forecast to surge to 21 million units per annum by 2005. Samsung will begin mass production of its ADSL chipsets in the first half of this year.


[ Terminology ]

■ ADSL (Asymmetric Digital Subscriber Line)

Conventional copper telephone lines are used to send and receive both voice calls and text data at the same time.
Transmission speeds of up to 8Mbps are possible, depending upon the distance between the subscriber and the telephone company.
The difference in the upload and download speeds and can be configured to deliver up to six megabits of data per second (6000K) from the network to the customer that is up to 120 times faster than dialup service and 100 times faster than ISDN.
ADSL enables voice and high-speed data to be sent simultaneously over the existing telephone line.
This type of DSL is the most predominant in commercial use for business and residential customers around the world.
Good for general Internet access and for applications where downstream speed is most important, such as video-on-demand.
ITU-T Recommendation G.992.1 and ANSI Standard T1.413-1998 specify full rate ADSL.

■ DMT (Discrete Multi-Tone Modulation)

A digital modulation IC using DMT technology divides data transmitted in one channel to various sub-channels, eliminating noise.

■ Controller

An MCU IC with an ARM core that is used exclusively for broadband communications.

■ AFE (Analog Front End)

An IC that converts digital signals analog and vice versa in order to transmit ADSL modem signals over a telephone line.
