DESCRIPTION
The Le87213A device, from the Zarlink Battery Direct™
family BD870 series devices, integrates two fully differential
line drivers, optimized feed back components, on-chip surge
protection diodes and bias control stages into a small
8 x 8 mm
needed to implement ADSL2+ downstream transmitters for two
lines. The Le87213A device is built on Zarlink’s high-voltage
process that allows for direct operation from a standard
telecom, negative battery supply (and a 3.3-V supply). In
contrast, typical line cards today supply the power to the line
drivers locally, via DC-to-DC converter modules. The
elimination of these additional modules translates into cost and
power savings at the system level. Operation from a
centralized source of power makes the Le87213A device a
unique, less costly, more efficient solution for xDSL line driver
applications. The Le87213A device is one of the most cost-
effective and easy-to-use parts for today’s xDSL applications.
