TMUX646: TMUX646

Nikhita J

Part Number: TMUX646

Tool/software:

We have recieved the TI EVK kit on last week,  we need interface with TFT with the help of MUX EVK , Also we have connected MIPI 2 lane to the EVK kit but it was not working.

When we were connecting MUX646 EVK,  Data signal, Clk signal we were not getting and also not working.

 

Note:

Without EVK when we were interfacing with TFT, it was working  MIPI 2 Lane as per our requirement.

We have made the connection MIPI module1 and interface with TFT but we were not getting any signal

We have made the connection MIPI module1 with 50E termination resistor  and interface with TFT but we were not getting any signal

    Hello Nikhita,

    Can you do basic functionality test on the EVM to check for faults?

    Turn on the mux and try to pass signals through, while monitoring it. 

    Please let me know the results you find.

    Thanks,

    Nir

    Hello Nir Gilgur,

    Functionality test on the EVM is done and found OK.

    1MHz, 2.5V continuous square signal is passed through input of (both channel A&B) TMUX646 and the same signal found on the output side (COM).

    But when we try to pass MIPI signals through TMUX646 EVK, TFT is turning on, but we could not see the exact image.

    All we can observe is RGB lines. Kindly support in this regard.

    Hello Nikhita,

    I am not familiar with TFT's what exactly is it? What is the application here, can you explain? 

    Have you tried passing MIPI signals through the EVM without the TFT? Are the signals found on the output good?

    Thanks,

    Nir
