xDSL Differential Line Driver
The ISL1557 is a dual operational amplifier designed for
VDSL2 and ADSL line driving in DMT based solutions. This
device features a high drive capability of 750mA while
consuming only 6mA of supply current per amplifier and
operating from a single 4.5V to 12V supply. The driver
achieves a typical distortion of -80dBc, at 150kHz into a 25Ω
load.
The ISL1557 is available in the thermally-enhanced
16 Ld QFN and 10 Ld HMSOP package and is specified for
operation over the full -40°C to +85°C temperature range.
The ISL1557 has control pins C
bias and enable/disable of the outputs. These controls allow
for lowering the power to fit the performance/power ratio for
the application.
The ISL1557 is ideal for ADSL2+, SDSL, HDSL2 and VDSL
line driving applications, including both 14.5dBm and 21dBm
applications.
