CEC

The CEC channel is a dedicated single pin bus and electrically translates to a bi-directional

buffer used to ensure that the electrical specs of the CEC are met even with high

capacitance on the single CEC line. The pull-up resistor of 26K? is integrated on either sides

of the buffer. The CEC is used for AV control of the electronic devices connected in a HDMI

cluster. The drive of the buffer is set to meet the requirements of the CEC. This is optionally

used for higher-level user functions such as automatic set-up tasks or tasks typically

associated with infrared remote control usage.

The CEC line is continuously monitored during the power-on state and is not monitored

during powered-off state. In powered off state, the CEC line should not be pulled low and it

should not affect the CEC communication between other devices. The maximum

capacitance on the CEC lines can be 7.2nF.
