GENEVA -- At next week's Supercomm trade show in Atlanta, STMicroelectronics Inc. will present details of a new chip set for central office applications in Asymmetric Digital Subscriber Line (ADSL) networks.
The new CopperWing product from ST reduces chip count and power dissipation, thereby cutting the cost per line in equipment, such as Digital Subscriber Line Multiplexers (DSLAMs), Digital Loop Carriers (DLCs), and central office line cards.
The new chip set integrates eight ADSL channels into two chips--the STLC60845 datapump and STLC60844 analog front-end IC. Combined with ST's line drivers, the chip set can support all functions from a Utopia interface in just 1.2-square-inches of board space at 1.1 watts per line.
The company expects to begin sampling the chipset in the third quarter of 2001, with production quantities available in 2002.
Developed in 0.18-micron CMOS technology, the STLC60845 comes in a 292-pin PBGA package. The STLC60844 is developed in 0.35-micron BiCMOS technology and comes in a 196-pin LFBGA package.
