VI_VSYNC[0]
C1
I
Video Input Vertical Sync. If VSP is set, then
VI_VSYNC[0] will define the start of the frame by
setting the vertical line counter to zero when
asserted. VI_VSYNC[0] is active HIGH if ISpol is
set, otherwise it is active LOW.

F4, E3, D1, E2,

H4, H3, H2, J4
O
Video Output Data. For 8-bit YCrCb video data
interleaved luma and chroma samples are output on
the VO_D[7:0] pins. The data order is either (Cb, Y,
Cr, Y) or (Y, Cb, Y, Cr), as selected by the Yfirst bit
in the video control register. For 16-bit YCrCb video
data luma and chroma samples are output on
VO_D[7:0] and VO_D[15:8] pins, respectively.
VO_CLK
H1
I/O
Video Output Clock. VO_CLK is the sample clock for
video output. The direction of VO_CLK is
programmable. Output data and control signals are
driven on the rising edge if olckr is set, otherwise
they are driven on the falling edge. For 8-bit video
output, VO_CLK is twice the pixel clock frequency
given the 4:2:2 I/O format and should be 27 MHz for
CCIR 601 format video. VO_CLK is the same as the
pixel clock frequency and should be 54 MHz for 8-bit
data and 27 MHz for 16-bit data. VO_CLK is
asynchronous to all other chip clocks, 0 to
74.25 MHz.
