National Semiconductor LMH6678 Low Power 2-Channel Central-Office xDSL Driver handbook
Update: 30 September, 2023
The LMH6678 is a low power 2-channel central-office xDSL driver that uses dual current feedback op amps to achieve a fixed gain of AV = +5.4, with high integration and low power consumption. It can provide 580 mW at 19.8 dBm line output power. The LMH6678 can also be put into a listen mode to maintain the termination for receive signals with 100 mW/Ch power dissipation. The LMH6678 has two separate 2-bit power control inputs compatible with 3.3V CMOS for each channel, which enable independent control of line status. When the drivers for both channels are shut off, power consumption drops to only 6 mW. Thermal Shutdown function protects the IC from a shorted line fault or system over temperature. The LMH6678 is available in a 5mm x 4mm 24-lead LLP package.
