16-Bit YCbCr, 16-Bit RGB, 24-Bit RGB Formats
with 2X Upscaling
When 16-bit YCbCr, 16-bit RGB data, or 24-bit RGB format
is selected and 2X upscaling is enabled, data is latched on
the rising edge of CLK2 while CLK is low. Overlay data is
latched on the rising edge of CLK2 while CLK is low. The
pixel and overlay input timing is shown in Figures 6-8.
As inputs, BLANK, HSYNC, and VSYNC are latched on the
rising edge of CLK2 while CLK is low. As outputs, HSYNC,
VSYNC, and BLANK are output following the rising edge of
CLK2 while CLK is high. CLK is one-fourth the CLK2
frequency.
