We are using ADV7441A as HDMI receiver and capturing different video resolutions.
We faced problem related to digitla video output of ADV7441A.
Case :- 1 Capturing video resolution of NTSC
Observation :- At output of ADV7441A, data is stable on falling edge of clock cycle.
The duty cycle is not 50%. (it is around 23%)
Figure 1 attached.
Case :- 2 Capturing 1080p60 video resolution
Observation :- At output of ADV7441A, data is stable on rising edge of clock cycle.
The duty cycle is 50%.
Figure 2 attached.
In both the cases the clock polarity resistor is 0x01.
Anyone has any idea about this kind of behaviour?
