VSYNC
70
Output
Vertical Sync. This video synchronous pulse is generated by the detection of a vertical
sync on the video input. In the absence of video theVSYNC rate is set by the over flow
oftheinternallineratecounter.Thispinisthree-statedafteraRESETorsoftwarereset
and should be pulled high through a 10K resistor.
FIELD
67
Output
Field Flag. When set (‘0’) this signals that an ODD field is presently being output from
the decoder. When cleared (‘1’) this signals an EVEN field. This flag will toggle when
no vertical sync is detected and 337 lines have elapsed. This pin is three-stated after
a RESET or software reset and should be pulled high through a 10K resistor.
ACTIVE
65
Output
Active Video Flag. This flag is asserted (‘1’) when the active portion of the video line
is available on the output port. This signal is always set during Burst Output data
mode. This flag is free running and synchronous to CLK. This pin is three-stated after
a RESET or software reset and should be pulled high through a 10K resistor.
TEST
36
Input
Test input. This pin is used for production test and should be connected to digital
ground.
