What EAV/SAV codes suit Analog Devices encoders?

Hi,

I am doing some content addition in an FPGA and need to know what EAV/SAV codes are used when  the NEWAVMODE bit is low (0x31[4]=0)?  It is not clear from the datasheet if where the vertical sync is when NEWAVMODE=0.  On page 46 of the datasheet (Rev F):

NEWAVMODE, New AV Mode, Address 0x31[4]
When NEWAVMODE is 0, EAV/SAV codes are generated to suit Analog Devices encoders. No adjustments are possible.

I am using the Eval board with the ADV7180LF and the ADV7191...

  • Hi Dave,

    Please find attached the datasheet of the encoder used on the ADV7180 40-pin LFCSP evaluation board. On page 80 you will find a diagram (Figure 107) of the timing expected by the encoder, which should correspond to the output of the ADV7180 when NEWAVMODE is set to 0.

    Best regards,
