Hi all,

 

Wonder if any of you experiment with this register and get the same result as mine?

 

Refer to ADV7441A_HW_revJ section 3.5.1 page 41.

 

If I understand the document correctly, when register 0x6A[bit5] = 1 the DLL is bypassed and we don't care the 5 LSB [4:0]

 

Matter of  fact, we experience strange behaves. Setting register 0x6A to 0x30 make the image more stable than setting it to 0x20

 

???
