      As ADV8005 hardware manual descriped, ADV8005 EXT OSD and TTL input pins need "Connect this pin to ground through a 4.7kΩ resistor" if unused. but it will increase much more resistors in PCB layout.

      Our Design need not EXT OSD and TTL input interface, Can i let these pins floating or connect them to GND directly?ADV8005 OSD INTERFACE.jpgADV8005 OSD INTERFACE1.jpg
