ADV7850 ADV7842 and OSD

Category: Datasheet/Specs
Product Number: ADV7850

Hi,

I want to use ADV7850/ADV7842 in my CVBS/SCART/RGB to HDMI project but I found that it doesn't have any OSD capabilities (I need just something very basic).

Q1: Do you have any single chip solution for this? I want avoid 7850+7625

Q2: On ADV7850 evaluation board schematic I see some kind of user input (UP/DOWN/LEFT/RIGHT/SEL). Is this for user interface display? If so, how this is realized for HDMI out? I can't download source code because I am not HDMI adopter.

I appreciate your support!

BR,

Szymon

  • Hi,

    Please find our response below,

       Yes, as per eval board schematic, ADV8003 can paired with other chipsets to support analog & digital IN/OUT.

    On 7850 eval board pcb layout I don't see ADV8003. Just ADV7850+LPC2387+keys

        This push button been available in the ADV8003 eval board and you could see the ADV7842 part in ADV8003 schematic.

       This eval board(ADV7850+LPC2387+keys) is specially designed for some additional audio support and here this Push button is mapped to "LPC2387 MCU" for user interface support like LCD but this need to be confirm.

       Also In manufacturing BOM report of ADV7850ebz_a.pcb, this button is not to be mounted. Please refer "adv7850ebz-mfg_a.xls".

    Thanks,
