Hello Team,

Please allow me to ask you if HDMI switch TMDS261B and TMDS361B are allowed to have cascaded connection. What our customer is willing to do is to increase HDMI input port count.

We know there is TMDS442 for 4 input switch, however, this device is not chosen for higher cost.

(Example)

Hi Kawai-san,

I just tested the cascading two TMDS361 and it failed, I can see the monitor listed but here is no video.
My guess is the distance between the two TMDS361 is very short and the signals is getting over-equalized, the best choice will be TMDS442.
