Objective data sheet
Fig 11. CEC output waveform
(1) Dotted line indicates effect without slew rate limiter.
10.5 Multiplexing
Up to 4 HDMI interface ports can exist on an HDMI receiver. The DDC and hot plug
signals are both needed to support various HDMI connectors, multiplexing and switching
of the TMDS lines. The CEC bus has to remain functional in order to detect activity such
as a brake in support.
