Part Number: TMUX1204
My customer is planning to use 2x TMUX1204 for eARC implementation.
Below are the exact of the eARC specification, may I know if there may be any concern? Currently we are using TMUX1204 for ARC implementation which is slower in data bandwidth.
Thanks for sending that information.
It looks like TMUX1204 does not have the bandwidth to support eARC at its maximum data rate.
Since you are using two 4:1 switches, a dual 4:1 with higher bandwidth might be a better fit. Please see the comparison of SN74CB3Q3253 and CD74HC4052 below:
We typically recommend the bandwidth of the switch be at least 2-3 times the max signal bandwidth. Take note that the bandwidth of CD74HC4052 may not be high enough for your application. SN74CB3Q3253 has a higher bandwidth with a max supply voltage rating of 3.3V.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
