TFP401A: the condition of CTL0/1/2/3

Toshiyuki

Part Number: TFP401A

Hi,

I would like to confirm the condition of CTL0/1/2/3. I understand the signals send additional information during the blanking periods. When there is no input for RX, the CTL* will output a all-zero signal by itself ?

Hi Elias-san,

Thank you for the reply. If there is no input during inactive display time, what does the CTL* output?

Best Regards,
Toshiyuki

Hi Elias-san,

Does the CTL* output high or low during inactive display? I apologize for rushing you, but could you please send me your reply as soon as possible?

Best Regards,

Hello,
During DE=low, they will output what was encoded on the video source, if you want them to output a low level then you have to ensure the video source is encoding the CTL=0.
