12V xDSL Differential Line Driver with

Enhanced Output Protection

Features

• 21dBm output power capability

• Drives up to 750mA from a +12V supply

• 20V differential output drive into 21Ω

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 25Ω

load. ISL1557A is design with stronger output clamps to

enhance protection against lightning transients.

P-P

• -80dBc typical driver output distortion at full output at

150kHz

• -75dBc typical driver output distortion at 4MHz

• -82dBc typical driver output distortion at 10MHz

• -79dBc typical driver output distortion at 17MHz

• Low quiescent current of 6mA per amplifier

The ISL1557A 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.

• Supply range

The ISL1557A has control pins C and C for controlling the

- For ISL1557AIUEZ 4.5V to 12V

- For ISL1557AIRZ ±2.25V to ±6V, 4.5V to 12V

bias and enable/disable of the outputs. These controls allow

for lowering the power to fit the performance/power ratio for

the application.

• 300MHz bandwidth

• Thermal shutdown

The ISL1557A is ideal for ADSL2+, SDSL, HDSL2 and

VDSL line driving applications, including both 14.5dBm and

21dBm applications.

• Pb-free (RoHS compliant)
