SVGA Subsampling Mode Timing
For the default SVGA line timing, a line starts when the HSYNC signal is de-asserted. The HSYNC signal
will be low for 32 PCLK clock cycles. After 50 PCLK clock cycles, DOUT [9:0] will output six cycles of
dummy pixel data followed by 800 cycles of image data, and followed by another 4 cycles of dummy pixel
data. Another 40 cycles later, the HSYNC signal will be de-asserted to start a new line. See Figure 11.

SVGA Subsampling Mode Frame Timing
For the default SVGA frame timing, the timing unit for the frame is derived from one line-time unit, which
are 900 PCLKs. Frame timing starts when the VSYNC signal is de-asserted. The VSYNC signal will be
low for 3 line-time units. Eight line-time units from the start of the frame, DOUT [9:0] will output 6 lines
of dummy pixel data, followed by 600 lines of image data, and followed by another 4 lines of dummy pixel
data. The VSYNC signal will be de-asserted again to start a new frame after another 32 line-time units. See
Figure 12.
