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
0
1
- 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)
