Hello,

 

My customer uses ADV7630 and they don't want to use external SPI Flash memory for EDID information.

Their system receive 3 HDMI signals and transmit 2 HDMI signals.

For designing this, they are considering to add 3ea of  EEPROM with EDID information between HDMI connectors and HDMI inputs of ADV7630.

Please refer attached schematics and let me know your opinions.

 

Q1) Is it possible cofiguration for using  EEPROM with EDID information between HDMI connectors and HDMI inputs of ADV7630?

 

Q2) Would you suggest any your recommended design with ADV7630 without external SPI flash memory?

 

Q3) Would you explain how to use internal EDID RAM and how to use external SPI flash memory?

 

Q4) Would you let me know where I can find the address information of each interfaces?

      For example, I2C address of EDID map seems to be 0x6C, but I can't find other address information of SPI interface.

     

 

 

Please advise me.

 

regards,

Se-woong
