The ISL15100 is a single port differential line driver developed

for Power Line Communication (PLC) applications. The device

is designed to drive heavy line loads while maintaining the

high level of linearity required in OFDM PLC modem links. With

15.5dBm of total transmit signal power into 100Ω line load,

the driver achieves -43dB average MTPR distortion across the

output spectrum up to 86MHz.

The ISL15100 has two bias current control pins (C0, C1) to

allow for four power settings (disable, low, medium, high). In

disable mode, the line driver outputs maintain a high

impedance in the presence of high receive signal amplitude,

so it doesn’t affect TDM receive signal integrity.

The ISL15100 is available in the thermally-enhanced 16 Ld

QFN and is specified for operation over the full -40°C to +85°C

ambient temperature range.
