Hello all,

Our customer uses ADV7393 at input of BT656 and output of NTSC.

Register 0x30 is default setting.

0X30[2] = 0 
  0:External HSYNC, VSYNC and field inputs 
  1:Embedded EAV/SAV codes

ADV7393 output video signal (NTSC) correctively when H and V input signal  is not connected.

 

Question
  1.  Does ADV7393 determine Timing of H and V from input of BT656  when H and V signal is not connected and 0x30[2]= 0?
  2. If we need any other settings, please let me know your advice.

Best Regards,
