The BD870 Series device is built on the Legerity high voltage process that allows for direct operation from a standard telecom, negative battery supply (and a 3.3-V supply). In contrast, today's typical line cards 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 BD870 Series a unique, less costly, more efficient solution for xDSL line driver applications.
