Dual Hdsl/sdsl Analog Front End Corporation

Burr-Browns dual Analog Front End AFE2124 chip greatly re- duces the size and cost of a DSL (Digital Subscriber Line) system by providing all of the active Analog circuitry needed to connect two digital signal processors to external compromise hybrids and line transformers. The AFE2124 is optimized for HDSL (High bit rate DSL) and for SDSL (symmetrical DSL) applications. Because the transmit and receive Filter responses auto- matically change with Clock frequency, the AFE2124 is particularly suitable for multiple rate DSL systems. The device operates over a wide range of data rates from 64kbps to 1168kbps. Functionally, each half of this unit consists of a transmit and a receive section. The transmit section generates Analog signals from 2-bit digital symbol data and Filters the Analog signals to create 2B1Q symbols. The on- board differential Line Driver provides a 13.5dBm signal to the telephone line. The receive section Filters and digitizes the symbol data received on the telephone line. This IC operates on a single 5V supply. The digital circuitry in the unit CAN be connected to a supply from 3.3V to 5V. It is housed in a 48-lead SSOP package. By Texas Instruments
