SN65DPHY440SS: Question about SN65DPHY440SS

Part Number: SN65DPHY440SS

Hello:

We want to reset the Ti sn65dphy440ss, but when the machine is dormant, pull down the RTS pin. When the machine wakes up, pull up the rst pin, but the screen cannot be lit, Please help check it, Thanks!!!

  • Hi,

    You don't need to pull up the RST pin, you can just release it from the pulldown and the DPHY440 internal pullup on the RST pin will pull it up. 

    What is the state of the input data and clock lane when RST is pulled up? Are they in LP or HS state?

    Thanks
    David
