GENERAL DESCRIPTION

The CopperWing12 ADSL Chipset family targets a

complete set of solution for Central Office (CO)

ADSL technology integrating also processing and

management capability to provide the best solu-

tion 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:

– 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 Re-

mote Unit or CO line cards; it provides also a gen-

eral 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 man-

agement operation. The chipset 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 applica-

tion. 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 guar-

antee high reach performance.
