Master devices can be placed on either bus. HDMI DDC applications for DVD/R and
LCD TV are shown in
transmitter or receiver is 3.3 V, while the DDC line is 5 V, PCA9527 behaves like a voltage
level shift, a buffer and long cable bus extender to ensure signal integrity for accessing the
EDID on the DDC line.
