SD TIMING
Mode 0 (CCIR-656)—Slave Option (Subaddress 0x8A = X X X X X 0 0 0)
The ADV7340/ADV7341are controlled by the SAV (start of active video) and EAV (end of active video) time codes embedded in the
pixel data. All timing information is transmitted using a 4-byte synchronization pattern. A synchronization pattern is sent immediately
before and after each line during active picture and retrace. If the S_VSYNC and S_HSYNC pins are not used, they should be tied to
V
Mode 0 (CCIR-656)—Master Option (Subaddress 0x8A = X X X X X 0 0 1)
The ADV7340/ADV7341 generate H and F signals required for the SAV and EAV time codes in the CCIR656 standard. The H bit is
output on S_HSYNC and the F bit is output on S_VSYNC .
