DATASHEET ISL1557A FN6568 Rev 3.00 12V xDSL Differential Line Driver with Enhanced Output Protection Mar 2, 2018 The ISL1557A is a dual operational amplifier designed for Features VDSL2 and ADSL line driving in DMT based solutions. This 21dBm output power capability device features a high drive capability of 750mA while consuming only 6mA of supply current per amplifier and Drives up to 750mA from a +12V supply operating from a single 4.5V to 12V supply. The driver achieves 20V differential output drive into 21 P-P a typical distortion of -80dBc at 150kHz into a 25 load. The -80dBc typical driver output distortion at full output at ISL1557A is designed with stronger output clamps to enhance 150kHz protection against lightning transients. -75dBc typical driver output distortion at 4MHz The ISL1557A is available in the thermally-enhanced 16 Ld QFN and 10 Ld HMSOP package and is specified for -82dBc typical driver output distortion at 10MHz operation over the full -40C to +85C temperature range. The -79dBc typical driver output distortion at 17MHz ISL1557A has two control pins (C and C ) for controlling the 0 1 Low quiescent current of 6mA per amplifier bias and enable/disable of the outputs. These controls allow for lowering the power to fit the performance/power ratio for Supply range the application. - ISL1557AIUEZ 4.5V to 12V The ISL1557A is ideal for ADSL2+, SDSL, HDSL2, and VDSL - ISL1557AIRZ 2.25V to 6V, 4.5V to 12V line driving applications, including both 14.5dBm and 21dBm 300MHz bandwidth applications.
