GENERAL DESCRIPTION  
The ADV®7324 is a high speed, digital-to-analog encoder on a  
single monolithic chip. It includes six high speed NSV video  
DACs with TTL-compatible inputs. It has separate 8-/10-,  
16-/20-, and 24-/30-bit input ports that accept data in high  
definition (HD) and/or standard definition (SD) video format.  
For all standards, external horizontal, vertical, and blanking  
signals, or EAV/SAV timing codes, control the insertion of  
appropriate synchronization signals into the digital data stream  
and, therefore, the output signal.
