m o Copper Wing12e .c U ADSL2+ Central Office (CO) Chipset: 4 t STLC61266/65 + STLC60454 + STLC60243 e e h S 1 General Description a at .D w w w DATA BRIEF throughput capability Dual GMII interfaces The Copper Wing12e ADSL2+ chipset targets a plete set of solution for Central Office (CO) ADSL technology integrating also processing and management capability to provide the best solution for ATM/IP DSLAM, ATM/IP mini DSLAM and "Pizza" boxes. The chipset integrates all ADSL/ ADSL2+ functions from ATM/IP interfaces to the line in three devices: - Two data pump chip options: - STLC61265: 12 channels ATM ADSL2+ Data Pump - STLC61266: 12 Channels ATM/IP ADSL2+ data Pump with embedded Cell Processor - STLC60454: 4 Ch ADSL/ADSL2+ AFE with integrated receiver and LP filters - STLC60243: Dual channel Line Driver The Copper Wing12e chipset is a 2nd Generation ADSL2+ CO Chipset with the following main feature upgrades versus the original Copper Wing12 chipset: - Significantly enhanced Cell Processor Figure 1.

The Modem Control Software runs entirely on the DMT Transceiver (no external memory needed for Interleave memory or modem SW): the line card host controller is in charge only of high-level management operation. The chipset is able to support not only the current ADSL standards, but also ADSL2 and ADSL2+ (12 channels). With only 1 square inches and less than 1 Watt per channel (in ADSL mode, 1.15W/line in ADSL2+ mode), the Copperwing12e chipset is one of the most petitive solutions for CO ADSL application. The chip set supports also ADSL2+ mode to deliver higher bit rate (24Mb/s) on short loops while...
