Advanced Information
Preliminary
Notes:
1. In Interlaced Mode, there are Even/Odd field different (t8). When In Progressive Scan Mode, only frame timing same as
Even field(t8).
2. After VSYNC falling edge, OV6620 will output black reference level, the line number is Tvs, which is the line number be-
tween the 1st HREF rising edge after VSYNC falling edge and 1st valid data CHSYNC rising edge. Then valid data, then
black reference, line number is Tve, which is the line number between last valid data CHSYNC rising edge and 1st
CHSYNC rising edge after VSYNC rising edge. The black reference output line number is dependent on vertical window
setting.
3. When in default setting, Tvs = 14 * Tline, which is changed with register VS[7:0]. VS[7:0] step equal to 1 line.
4. When in default setting, Tve = 4 * Tline for Odd Field, Tve = 3 * Tline for Even Field, which is changed with register VE[7:0].
VE[7:0] step equal to 1 line.
