HDMI receiver and converter to 24-bit RGB

Category: Hardware
Product Number: AD9398 / ADV7611
I need to select a HMDI receiver par which can convert HDMI to 24-bit RGB signal.
The display module is ECX336CN which can operate at 1.8V. 
Came up with AD9398 which can operate at 1.8V so I don't need signal level shifter part. But AD9398 is AD9398 is not recommended by Analog Device for new designs and no technical support for that.
The alternative part is AD7611.Looking at the datasheet the minimum digital Output High Voltage is 2.4V which is higher than absolute range of ECX336CN. 
1- is there any HDMI receiver can support 24-bit REG (1.8V)?
2- if the only option is AD9398, can I get some technical support for the schematic?
3- Going with AD7611 root, required level shifter for my application?
thanks in advance for help.

The AD9398 is not recommended for new designs.  I recommend the ADV7611 even with its 3.3V digital outputs.  IF you really want to use the AD9398 I can get you a reference schematic however support for the part maybe lacking due to its age and people have moved on.  We currently have full support from the ADV7611

  • Hi,

      Please note AD9398 is not recommended for new designs and has not been recommended for new designs in quite a while.

      But most of our receivers such as ADV7610,ADV7611,ADV7612, ADV7619 ,ADV7625,ADV7604 can support 24 digital bus.But most of them can output high voltage as 2.4V 

    So kindly use level shifter accordingly.




  • Hi 

    thanks for reply.

    is it possible please to let me have part number of level shifter you recommend to be used for RGB and with AD7611?

    Also any design reference schematic.


  • Thanks for your reply,

    Understood and will take your advice.

  • Hi,

       Could you please check with other community about level shifter (for example - (+) Interface and Isolation - EngineerZone ( Please check frequent level shifter the customer used at their end) since i am not aware about that. Sorry.
