Hai,
I am doing a switcher with HD3SS215 chip. I got problem while i am using the chip as a 2x1 switcher i.e; 2 inputs and one output.
1) In the output only port A signal is displaying even if i change the DX_SEL value it is not displaying port B signal.
2) Whenever i connect the HDMI cable from monitor to port C, the voltage at HPD pin of port C is about 5V and without connecting HDMI cable at port A it generating voltage at HPD pin of port A of about 3.3V.... and this case is not happening at port B
3) Whenever i connect HDMI cable at port B their voltage at HPD pin of port B but DDC signal pins have a volatge of 5V and remaining signal pins are generating 0V
===================================================================================================================================================================
In the below schematic i have made some modifications:
1) I have removed Ground connection from every HDMI connector 14th pin and shorted 20,21,22,23 pins which are present on mounting side of the connector body to ground directly.
2) In the schematic file port C D2(P), D2(N) are alternated with D0(P),D0(N) as per HD3SS215 datasheet.
3) In the first point, as i mentioned i have removed grounding from 14th pin.. the ground does not connected for port B connector. So, i added that ground connection from port A connector ground via.
