Description
The Le87402 is a 2-channel line driver designed to
work in Home Plug Alliance HPAV2 systems, G.HN
and MOCA.
Each channel can be enabled independently allowing
multiple-in, multiple-out (MIMO) or single-in, single-out
(SISO) operations.
The Le87402 can drive a line impedance of 100 Ω
down to 12 Ω through a proper transformer and
delivers superior performance with power efficiency
using Class GH operation.
