MUNICH -- In a move to fill out its "one-to-shop" for digital subscriber line (DSL) systems, Infineon Technologies AG today introduced a single-chip line driver/analog frontend device for asymmetric DSL modems. The new 80-pin chip boosts integration and cuts power consumption in ADSL systems, which are beginning to grow in high volumes, said the Munich-based company.
According to Infineon, the PEB 22715 draws just 800 millwatts during full transmit power at maximum ADSL bit rates.
The device includes the analog frontend, line driver digitally-controlled crystal oscillator (DCXO) and filters. Infineon said the chip is the first to integrate the DCXO function, and it eliminates a separate expensive voltage controlled oscillator (VXCO) to handle modem timing recovery.
The launch of the single-chip line driver/analog frontend device comes at a time when ADSL is entering its the growth phase and other standards are beginning to move forward in the initial introduction stage, said Ben Runyon, product marketing manager for xDSL devices at Infineon in San Jose.
Infineon aims to cover the xDSL market with a product portfolio serving four versions of digital subscriber line technologies--all with different speeds and ability to transmit over a range of distances. Infineon's one-stop-shop supports: ADSL (for residential markets); symmetric high-bit-rate DSL, or SHDSL (for small-to-medium sized businesses); very-high-speed DSL, known as VDSL (for video to home and multidwelling/multitenant units); and ISDN-based DSL, dubbed IDSL (for long-distance, but slower connections in areas not currently served by other xDSL links).
"As the market matures, we believe many large corporations will want to reduce their vendor base in xDSL," Runyon said. "But we also believe there is no one DSL technology for all applications. Therefore, Infineon has decided to cover the entire market with the four flavors of xDSL and is teaming with partners to do that.
For example, the Munich chip supplier today also announced a partnership with Ishoni Networks Inc. of Santa Clara, Calif., which will work with Infineon to develop a reference design for integrated access device applications using an SHDSL chip set. The SHDSL standard is expected to be finalized in February 2001 and that version of xDSL will begin to move into the market growth phase, Runyon said.
ADSL is now moving into the mass deployment phase and expected to reach 800 million copper lines worldwide, according to Infineon. About 180 million of those ADSL lines are in the United States, estimated Runyon.
In quantities of 100,000, the new ADSL line driver/analog frontend device sells for $9.50. Volume shipments will start in the fourth quarter of 2000. Samples are now available.
