HDMI? Port
HDMI 1.4 - ESD & Overcurrent Protection
Solution Products
Objective
HDMI 1.4 is a hot-pluggable interface
combining video, audio & Ethernet signals.
Voltages are 5 V or lower and the bandwidth
is 340 MHz. This solution privides HDMI 1.4
ports with protection against ESD and short
circuits without impairing the transmission
of power or data
