DATASHEET ISL15110 FN8282 Rev 1.00 PLC MIMO Line Driver Apr 6, 2018 The ISL15110 is a dual port differential line driver developed Features for Power Line Communication (PLC) Multi Input Multi Output Dual differential drivers (MIMO) applications. MIMO PLC requires transmission on one or two pairs of Phase, Neutral, and Ground wires. The device is 50MHz broadband PLC G.hn designed to drive heavy line loads while maintaining a high Enable/disable control pins for TDM operation level of linearity required in OFDM PLC modem links. With -50dBc average MTPR distortion 15.5dBm of total MIMO transmit signal power (12.5dBm per each pair) into a 50 line load, the drivers deliver -50dB Single supply +12V nominal operation average MTPR distortion across the output spectrum. Enhanced surge current handling capability Each of the two differential drivers has a control pin to enable Thermally enhanced 20 Ld QFN package and disable its differential output. These controls allow for Enable port control voltage <0.7V independent TDM operation of the two differential drivers, as required in ITU-T MIMO G.hn and related standard based PLC Disable port control voltage >1.7V applications. In disable mode, the line driver output maintains a high impedance characteristic to preserve TDM receive Applications signal integrity. Home networking over power lines The ISL15110 includes an external IBIAS pin for quiescent ITU-T G.hn (G.9963) MIMO PLC current flexibility. Grounding the pin in single supply designs gives the nominal currents in the Electrical Specifications table starting on page 5, while inserting a resistor from pin to ground can be used to scale down the quiescent current for both ports. The ISL15110 is available in the thermally-enhanced 20 Ld QFN and is specified for operation across the full -40C to +85C temperature range.
