To request the full datasheet, please visit www.intersil.com/products/ISL1557A Data Sheet March 12, 2009 12V xDSL Differential Line Driver with
Enhanced Output Protection FN6568.1 Features 21dBm output power capability The ISL1557A 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 25пЃ—
load. ISL1557A is design with stronger output clamps to
enhance protection against lightning transients. Drives up to 750mA from a +12V supply 20VP-P differential output drive into 21пЃ— -80dBc typical driver output distortion at full output at
150kHz -75dBc typical driver output distortion at 4MHz -82dBc typical driver output distortion at 10MHz The ISL1557A is available in the thermally-enhanced
16 Ld QFN and 10 Ld HMSOP package and is specified for
operation over the full -40В°C to +85В°C temperature range.
The ISL1557A has control pins C0 and C1 for controlling the
bias and enable/disable of the outputs. These controls allow
for lowering the power to fit the performance/power ratio for
the application. -79dBc typical driver output distortion at 17MHz The ISL1557A is ideal for ADSL2+, SDSL, HDSL2 and
VDSL line driving applications, including both 14.5dBm and
21dBm applications. Thermal shutdown Low quiescent current of 6mA per amplifier Supply range
