DESCRIPTION
Burr-Brown’s dual Analog Front End 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 AFE2126 is optimized for HDSL (High bit rate
DSL) and for SDSL (symmetrical DSL) applications.
The AFE2126 is particularly suitable for multiple rate
DSL systems because the transmit and receive filter
responses automatically change with clock frequency.
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.
