  • SN65DP149: SDA, SCL and HPD SRC/SNK pins floating?

    TI Thinks Resolved
    Part Number: SN65DP149 Hello, Working with the SN65DP149RSBT HDMI Re-Driver/Re-Timer which is connected to a FPGA. We currently have the DDC connections directly through to the FPGA rather than passing through the chip. Is there is any consequence of…

  • SN65DP149: About DVI mode

    Resolved
    Part Number: SN65DP149 Hi team I have a question. It says that I can set pin 23 (HDMI_SEL) of SN65DP149 to High to enable DVI mode, but what does that change? Does it remove the audio data, etc. from the TMDS signal? Thank you. maru

  • SN65DP149：SN65DP149能否替代PS8402A?

    TI Thinks Resolved
    Part Number: SN65DP149 第一次来TI的论坛，来试试下，最近想用SN65DP149来替代PS8402A的芯片，看了两者规格书和PIN脚定义，SN65DP149工作需要用到3.3V和1.1V，VSADJ的下拉电阻6.5K。PS8402A工作需要用到3.3V和1.5V，REXT的下拉电阻为4.99K，那么我调整后应该是能正常工作的，但是发现只是偶尔出图，并且出图也是1080P@60Hz，达不到4K@30Hz。不知道什么原因，请大神帮忙分析下原因，谢谢了。
