Sixth-generation ADSL chipset
crams in more lines

Texas Instruments is claiming the highest 'true' density in the industry for its latest ADSL solution

The AC6 chipset supports the most lines and the lowest power consumption in the smallest area, three critical items for central office (CO) applications, which provides a greater overall line card port density over competitive solutions. TI's integration capabilities and total system approach enable manufacturers and service providers to cost-effectively increase the number of lines supported in the CO to serve more ADSL customers worldwide with support of Annex A, B and C.

As an octal ADSL infrastructure chipset, the AC6 provides manufacturers greater all around line card density compared with existing chipsets on the market which claim highest density based only on the number of lines the chipset supports without factoring in power consumption or board space.

Measurement of overall density is put to the test when comparing the AC6 chipset with 12- or 16-port competitive solutions for a typical 48-port line card.

On average, the AC6 can increase the number of ports supported by 20% compared with 16-port solutions on the market today, for the same board form-factor.

This is accomplished with a maximum power of 950mW and an area of 7cm2 per line for the AC6 chipset, which also takes system considerations into account in the design providing more power and space savings for the equipment manufacturer.

'Density is not necessarily based on the number of ports per chipset, you have to consider power consumption, board space and number of ports supported', said IDC Analyst Ken Furer.

'Through aggressive integration, true density products like TI's new AC6 chipset will help drive cost-effective solutions for OEMs and service providers'.

The AC6 achieves density improvements by using advanced power management and high levels of integration to enable more ADSL ports to be supported per line card.

Utilizing a set of power management techniques (digital cutback, Qmode and customised plug-in power modules), the AC6 monitors and dynamically maintains and adjusts the required power levels for every loop in the system enabling power well below 950mW per port.

Additionally, the AC6 leverages TI's expertise in system integration to reduce the RBOM (rest of bill of materials) cost by 40% and provides in-band management, eliminating the need for a host processor, which equates to a total system cost savings of up to $40 per line card.

'ADSL equipment manufacturers are looking for chipsets that provide greater overall line card density to reduce costs and enable more subscribers to be supported.

The AC6 chipset demonstrates TI's in-house expertise to provide the best ADSL infrastructure chipsets on the market', said Bill Eversole, general manager of TI's DSL Business.

'Only TI has the digital, analogue, software and system support core competencies required to provide tailored solutions to manufacturers and service providers looking to expand the ADSL market'.

The AC6 chipset supports all worldwide ADSL standards and offers the highest performance based interoperability, to meet Category-I, Category-II and DSL Forum WT-062 requirements.

The first of a family of sixth-generation ADSL infrastructure chipsets, the AC6 is scheduled to sample in 1Q of 2002, with volume production scheduled for 2Q of 2002.
