DATASHEET
ISL15110
PLC MIMO Line Driver
The
ISL15110
is a dual port differential line driver developed
for Power Line Communication (PLC) Multi Input Multi Output
(MIMO) applications. MIMO PLC requires transmission on one
or two pairs of Phase, Neutral, and Ground wires. The device is
designed to drive heavy line loads while maintaining a high
level of linearity required in OFDM PLC modem links. With
15.5dBm of total MIMO transmit signal power (12.5dBm per
each pair) into a 50Ω line load, the drivers deliver -50dB
average MTPR distortion across the output spectrum.
Each of the two differential drivers has a control pin to enable
and disable its differential output. These controls allow for
independent TDM operation of the two differential drivers, as
required in ITU-T MIMO G.hn and related standard based PLC
applications. In disable mode, the line driver output maintains
a high impedance characteristic to preserve TDM receive
signal integrity.
The ISL15110 includes an external IBIAS pin for quiescent
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 -40°C to
+85°C temperature range.
