STLC60454

The CopperWing12 ADSL STLC60454 family targets a complete 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 STLC60454 options:
STLC61255: 12 channels ATM ADSL Data Pump
STLC61256: 12 Channels ATM/IP ADSL data Pump with embedded Cell Processor
STLC60454: 4 Ch ADSL/ADSL2+ AFE with integrated receiver and LP filters
STLC60243: Dual channel Line Driver CopperWing12 chipset family provides Ethernet and ATM interfaces to fit IP and ATM based Remote Unit or CO line cards; it provides also a general purpose controller to allow the development of controller-less line cards.

The Modem Control Software runs entirely on the DMT Transceiver (no external memory needed for Interleave memory nor modem SW): the line card host controller is in charge only of high-level management operation. The STLC60454 is able to support not only the current ADSL standards, but also ADSL2 and ADSL+ (12 channels).With only 1 square inches and less than 1 Watt per channel (in ADSL mode, 1.15W/line in ADSL+mode), the Copperwing12 chipset is one of the most competitive solutions for CO ADSL application.The chip set supports also ADSL+ mode to deliver higher bit rate (24Mb/s) on short loops while with Reach Extended ADSL is able to guarantee high reach performance.
