Chip availability or chip detail for AHD converter

Thread Summary

The user inquires about AHD converters for MIPI DSI, HDMI, and LVDS inputs. The final answer confirms that no single-chip solution exists for MIPI DSI to AHD or LVDS to AHD. For HDMI to AHD, a two-chip solution is required: ADV761x/ADV784x for HDMI to pixel bus conversion and ADV800x for pixel bus to AHD conversion. The Serial Video Rx in ADV800x is designed for chip-to-chip connections and does not support direct HDMI input.

Hi ADI,

we are looking for AHD converter, If you have any converter with following specification
1. Mipi DSI to AHD
2. HDMI to AHD
3.LVDS to AHD 
etc ..

  • Hi,

     Kindly note that,We need to go for two chip solution for converting HDMI to Analog HD output. 

       ADV761x/ADV784x - It will convert HDMI to Pixel bus Output.

       ADV800x - It will take Pixel input to AHD Output.

    Here ADV761x converts input HDMI to Pixel port output and ADV800x takes the pixel port output of ADV761x as input and Outputs the AHD Video . For more information please refer the design support files of ADV761x and ADV800x.

  • Hi Poornima Subramani

    I go through  Datasheet of ADV8005/ 8003 there they mention we can provide HDMI input in Serial Video Receiver port, If there  why we need HDMI to pixel bus Converter first and then Pixel bus to HDMI converter, Instead of that we Directly give HDMI input to  ADV8005/ 8003 to get AHD output?. Can you please give me the clarity in that.

  • Hi,

       Kindly note that, It's not possible to achieve single chip solution with ADV800x part for 'HDMI to AHD' conversation Since Serial Video Rx accommodates inter-chip transfer of data over an HDMI compatible interface (for example, from an HDMI (Rx) such as ADV7850 or transceiver such as ADV7623).

       Note: Serial video receiver is designed for chip-to-chip connection only and, as such, does not offer any DDC lines to facilitate HDCP or EDID operations so two chip is required for converting .

    Thanks,

  • Hi Poornima,

    You have any EVK to convert HDMI to AHD for validation
