SECOND SOURCED BY BROOKTREE

DESCRIPTION
Burr-Brown’s Analog Front End greatly reduces the
size and cost of an HDSL or MDSL system by provid-
ing all of the active analog circuitry needed to connect
the Brooktree Bt8952 HDSL digital signal processor
to an external compromise hybrid and a 1:2 HDSL line
transformer. All internal filter responses as well as the
pulse former output scale with clock frequency—
allowing the AFE1103 to operate over a range of bit
rates from 196kbps to 1.168Mbps.
Functionally, this unit is separated into a transmit and
a receive section. The transmit section generates, fil-
ters, and buffers outgoing 2B1Q data. The receive
section filters and digitizes the symbol data received
on the telephone line and passes it to the Bt8952. The
HDSL Analog Interface is a monolithic device fabri-
cated on 0.6
μ
CMOS. It operates on a single +5V
supply. It is housed in a 48-pin SSOP package. This
unit is second sourced by Brooktree’s Bt8921.
