Infineon Launches SOCRATES 4 the Industry's Lowest Power Multi-Channel SHDSL Transceiver for High Density Line Cards

Jun 4, 2001 | Market News

Atlanta, June 4, 2001 –– Infineon Technologies (FSE/NYSE: IFX), a leading supplier of communications integrated circuits, today announced at Supercomm the availability of SOCRATES™ 4, the industry’s lowest power, symmetrical high-bit rate digital subscriber line (SHDSL) transceiver that combines four complete SHDSL channels, analog and digital, on a single device, making it ideal for multi-channel applications such as high-density linecards used in DSLAMs and DLCs.

“The growing demand for higher density systems is driving system vendors to seek higher integration and lower power silicon solutions. The SOCRATES™ 4 enables our customers to reduce costs by optimizing these factors“, said Christian Wolff, vice president of Infineon’s communications business group and general manager of the carrier access business unit. “With our new device service providers such as ILECs, CLECs and ISPs can now offer the large business and SOHO markets more competitive solutions over existing copper wires.”

Based on Infineon’s highly reliable SOCRATES™ single channel transceiver announced in April 2000, SOCRATES™ 4 offers the industry’s lowest chip count and a reduced number of passive components. The device also boasts the lowest power consumption on the market at less than 700mW per channel a figure 30 percent below competing solutions.

SOCRATES™ 4: Integrated Multi-channel Device
Infineon is the market leader for integrated features within a single SHDSL package. By combining the analog front end, line driver, microcontroller, tunable hybrid, framer, HDLC controllers and memory into a single 388 pin BGA package, SOCRATES™ 4 reduces the board space required on high density linecards significantly. For example, a 72 channel linecard requires only 1 square inch per port, saving customers overall system costs by reducing the amount of silicon real estate used. In addition to DSLAMs and DLCs, the device can also be used in multi channel IADs, E1/T1 replacement as well as 4-wire repeaters.


SHDSL features a bit rate from 192 kbps up to 2.3 Mbps and is standardized by ITU G.991.2 and ETSI TS 101524. SHDSL provides roughly 25 percent more loop reach than currently deployed 2B1Q based SDSL technology and offers excellent spectral compatibility with other DSL services like ADSL. With interoperability an increasingly important requirement, SHDSL is well positioned to become the successor to all existing symmetric DSL technologies such as HDSL, HDSL 2 and SDSL.

Pricing and Availability

The SOCRATES™ 4 SHDSL single-chip transceiver, part number PEB 242622, is now available in sample quantities accompanied by a complete firmware and evaluation package. A 32-channel DSLAM density study is also available. Housed in a 388-pin BGA package, SOCRATES™ 4 is priced at US$20 per channel and will start shipping in volume quantities in Q3/2001.
