t4U.com CopperWing12eADSL2+ Central Office (CO) Chipset:
e STLC61266/65 + STLC60454 + STLC60243
e DATA BRIEF
Sh1 General Description
taThe CopperWing12e ADSL2+ chipset targets a
acomplete set of solution for Central Office (CO)
.DADSL technology integrating also processing and
wmanagement capability to provide the best solu-
wtion for ATM/IP DSLAM, ATM/IP mini DSLAM and
w m"Pizza" boxes. The chipset integrates all ADSL/
ADSL2+ functions from ATM/IP interfaces to the
oline in three devices:
.c■ Two data pump chip options:
– STLC61265: 12 channels ATM ADSL2+
Data Pump
U– STLC61266: 12 Channels ATM/IP ADSL2+
t4data Pump with embedded Cell Processor
■ STLC60454: 4 Ch ADSL/ADSL2+ AFE with
integrated receiver and LP filters
e■ STLC60243: Dual channel Line Driver
eThe CopperWing12e chipset is a 2nd Generation
ADSL2+ CO Chipset with the following main fea-
hture upgrades versus the original CopperWing12
chipset:
S● Significantly enhanced Cell Processor
throughput capability
● Dual GMII interfaces
● ATM Header compression support
● EFM PTM support (TC 64/65)
CopperWing12e chipset provides Ethernet and
ATM interfaces to fit IP and ATM based Remote
Unit or CO line cards.
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 man-
agement 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 competitive solutions for CO ADSL applica-
tion. The chip set supports also ADSL2+ mode to
deliver higher bit rate (24Mb/s) on short loops
while with Reach Extended ADSL is able to guar-
antee high reach performance.

quired 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 exter-
nal filter requirements. Each single channel can be
put in power down mode and provides program-
mable filters in the receive path. No external re-
ceiver is required.
