Centillium Communications announced an ADSL2/ADSL2plus-compatible chipset for Customer Premises Equipment (CPE), which it claims can deliver data rates up to 50 Mbps or extend the reach of ADSL up to 22,000 feet. The Palladia 220 is a router-on-a-chip solution integrating Centillium’s eXtremeDSLMAX technology. The chipset features a 200MHz RISC processor and hardware accelerators for packet processing, a high-speed PCI/Cardbus interface, 10/100 Ethernet, USB and a number of serial interfaces. The Palladia 220 includes a newly designed analog front-end to accommodate the extended spectrum operation enabled by the eXtremeDSLMAX technology. It also features high-resolution analog-to-digital and digital-to-analog converters and an exceptionally low-noise floor. It complements Centillium’s recently announced Maximus central office chipset.

- In May 2003, Centillium Communications unveiled its “Maximus” 12-channel, central office (CO) chipset compliant with the ITU-T G.992.1 (G.dmt), G.992.2 (G.lite), G.992.3 (G.adsl2) and G.992.5 (G.adsl2plus) standards. The company claims its eXtremeDSLMAX technology is able to deliver up to 50 Mbps of downstream bandwidth for short loops, or reach customers at distances up to 22,000 feet from the central office, while maintaining full backward compatibility with over 30 million deployed ADSL modems. ADSL2plus standard offers downstream data rates of up 24 Mbps over short-to-medium length loops. Centillium’s Maximus delivers up to 50 Mbps by leveraging a “quad stream” feature that uses frequency spectrum from 138 Khz to 3.75 MHz. The Maximus chipset supports upstream rates of up to 3 Mbps using frequency spectrum from 25 Khz to 276 Khz.
