DATA BRIEF

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 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:
– 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 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 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.

DESCRIPTION
The STLC61255 twelve channels ADSL Transceiver
is the key component for Asymmetrical Digital Subscriber Line (ADSL) Central Office modem implementation. The highly integrated device supports
category II ADSL functionalities, including trellis coding and echo cancellation. The device embodies 6 independent dual transceivers optimized for Central
Office operation, with bit rates of up to 3.0 Mbps up-

stream and 24 Mbps downstream. This device is ideal for power and area sensitive Central Office
equipment, providing highest performance and density while meeting all telecom grade equipment requirements. The STLC61255 is designed for minimal
host controller intervention during runtime operation.
Combining this feature with additional management
interfaces such as the serial host interface and the Inband Utopia management interface provides many
alternatives for designs that significantly reduce operation complexity and cost. Cost saving can be
achieved by using a singe low-cost controller to support high-density line-cards, saving the need for onboard flash memory or even the entire host processor environment. The STLC61255 host interface provides a full sup-port of the ADSL MIB, and a rich set
of statistic information and programmable fault
alarms.

DESCRIPTION
The STLC60454 is a 4 channel ADSL AFE. It implements four analog transceiver functions required for
a central office modem. It connects the digital modem
chip with the line driver and hybrid balance circuit.
This 4 channel AFE has been designed with high dynamic range in order to greatly reduce the external filter requirements. Each single channel can be put in
power down mode and provides programmable filters
in the receive path. No external receiver is required.
