The BD870 Series 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, 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.

Features & Benefits

• Two-channel differential line drivers
• Low power
  • 720 mW per channel, typical (ADSL+ Mode) (showtime, >5 kft 26 AWG cable, not including load)
  • 670 mW per channel, typical (ADSL Mode) (showtime, >5 kft 26 AWG cable, not including load)
• Operates directly from a typical telecom power supply without a DC-to-DC converter and a 3.3 V supply
• Integrated lightning and surge protection
• 50 V_P differential signal at the driver outputs
• I_OUT max 95 mA into 100-? load
• MTPR of 70 dB, typical
• Minimum external component count ~ 10 discretes per channel
• Can output 20.8 dBm power into 100-? load with step down transformer
• Thermal shutdown
• Small footprint
  • 32-pin (8 x 8 mm) QFN
