In Figure 34, the DTV does not have the capability of handling CEC signals, but allows CEC signals to pass over
the CEC bus. The source selection is done by the control command of the DTV. The user cannot force the
command from any audio/video product on the CEC bus. The selected source reads the E-EDID data after
receiving an asserted HPD signal. The microcontroller loads different CEC physical addresses while changing
the source by means of the S1 and S2 pins.
When the DTV system is in standby mode, the sources do not read the E-EDID memory because the 1-k
pulldown resistor keeping the HPD_SINK input at logic low forces all HPD pins to output logic-low to all sources.
The source does not read the E-EDID data with a low on HPD signal. However, if reading the E-EDID data in the
system standby mode is preferred, then TMDS361 can still support this need.
The recommended configuration sequences are:
1. Apply the same 3.3-V power to the VCC of TMDS361 and the TMDS line termination at the HDMI receiver
2. Because the TMDS361 has clock-detect circuitry and there is no valid input TMDS clock in the standby
mode, TMDS361 draws significanty less current.
3. Set S1 and S2 to select the source port which is allowed to read the E-EDID memory.
Note that if the source has a time-out limitation between the 5-V and the HPD signals, the foregoing configuration
is not applicable. Uses individual EEPROMs assigned for each input port, see Figure 35. The solution uses
E-EDID data to be readable during system power-off or standby-mode operations.
