Single Port, PLC Differential Line Driver
ISL15100 Features 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 100О© line load,
the driver achieves -43dB average MTPR distortion across the
output spectrum up to 86MHz. Single differential driver 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 -40В°C to +85В°C
ambient temperature range. 100MHz Broadband PLC G.hn, EOC, HomePlug AV2 Control pins for enable/disable and supply current selection High output impedance when disabled for TDM operation -43dBc average MTPR distortion at full line power Single +12V or bipolar ±6V nominal supplies High surge current handling capability Applications Power Line Communication differential driver Pin compatible upgrade to ISL1571IRZ Related Literature AN1325 “Choosing and Using Bypass Capacitors”
