  • ADV7619 : Question of ADV7619 Software Manual.

    Hi all.

    I confirm the update of ADV7619 SWM.
    And I found that there are multiple difference between HUG and SWM.

    This bit is not describe in HUG.
    When will HUG update this description?

    Hi,

     PC generally do not work unless they see a valid EDID &  PC will only recognize a sink only when they detect an valid EDID So please make sure are you configuring with a valid EDID.

    Please make sure with below when bringing up the board.
        1) Disconnect…

  • RE: ADV7619. 1600x1200 120MHz

    Hi,

     As per ADV7619 Reference Manual(UG-237), ADV7619 part can "Supports all display resolutions up to UXGA 1600 x 1200 at 60Hz, 10-bit".

     Here also we are not getting any video output for 1600x1200@120Hz using our ADV7619 eval board.

    Thanks…

  • ADV7619

    I have couple more questions on ADV7619:

    (1)    Does the chip defaults to 4:4:4 RGB mode?

    (2)    If there is any automatic resolution change, while using the chip, any rough estimate of how much software overhead it requires?

    Thanking you in advance.

  • 请教,ADV7619 作为接收端口,EDID 信息是否可以写在 ADV7619 的内部 RAM?

         做为HDMI的接收端口,都要给HDMI发送端提供EDID信息,用于向HDMI发送端表明接收端可以接收哪种格式和分辨率的HDMI信号。

         在以前的设计中,EDID信息都是存储在接收端的一块EEPROM芯片中。我看到ADV7619FEATURE中提到支持内部的EDID,并且从UG237文档中看到ADV7619内部确实有一块RAM用于存储EDID信息。


              我的问题是,有了这块内部的EDID存储区,是否就可以省去原来设计中的EEPROM芯片?虽然ADV7619掉电后,这片RAM中的EDID信息会丢失…
