ISL1557IRZ-EVAL

xDSL Differential Line Driver Evaluation Board

The ISL1557IRZ-EVAL evaluation board is used to evaluate the features of the ISL1557 dual operational amplifier which is ideal for ADSL2+, SDSL, HDSL2, and VDSL line driving applications, including both 14.5dBm and 21dBm.

The ISL1557 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.

Features

  • Full-range industrial temperature (FRZ only): -40 °C to +125 °C
  • 21dBm output power capability
  • Drives up to 750mA from a +12V supply
  • 20VP-P differential output drive into 21Ω
  • -80dBc typical driver output distortion at full output at 150kHz
  • -75dBc typical driver output distortion at 4MHz
  • -71dBc typical driver output distortion at 10MHz
  • -75dBc typical driver output distortion at 17MHz
  • Low quiescent current of 6mA per amplifier
  • 300MHz bandwidth
  • Thermal shutdown
  • Pb-free (RoHS compliant)

Applications

  • VDSL2 line drivers
  • Power line communications line drivers
  • ADSL2+ CPE line driving
  • G.SHDSL and HDSL2 line drivers
