GENERAL DESCRIPTION
The ADV
single monolithic chip. It includes six high speed NSV video
D/A converters with TTL compatible inputs.
The ADV7314 has separate 8-/10-/16-/20-bit input ports that
accept data in high definition and/or standard definition video
format. For all standards, external horizontal, vertical and
blanking signals, or EAV/SAV timing codes control the inser-
tion of appropriate synchronization signals into the digital data
stream and therefore the output signal.

... Mode 0 (CCIR-656)—Slave Option (Timing Register 0 TR0 = The ADV7314 is controlled by the SAV (start active video) and EAV (end active video) time codes in the pixel data. All timing information is transmitted using a 4-byte synchronization pat- tern. A synchronization pattern is sent immediately before and after each line during active picture and retrace ...

... Mode 0 (CCIR-656)—Master Option (Timing Register 0 TR0 = The ADV7314 generates H, V, and F signals required for the SAV (start active video) and EAV (end active video) time codes in the CCIR656 standard. The H bit is output on S_HSYNC, the V bit is output on S_BLANK, and the F bit is output on S_VSYNC pin ...

... A transition of the field input when HSYNC is low indicates a new frame, i.e., vertical retrace. The BLANK signal is optional. When the BLANK input is disabled, the ADV7314 automatically blanks all normally blank lines as per CCIR-624. HSYNC is input on HSYNC, BLANK on S_BLANK, and FIELD on S_VSYNC. ...
