gain luminance of RGB (Cr, Y and Cb) output, ranging from (1
Suggested nominal value = 6 (11010b), depending on external application.
gain colour difference of RGB (Cr, Y and Cb) output, ranging from (1
Suggested nominal value = 6 (11010b), depending on external application.
input data is twos complement from MP1 input port (encoder path)
input data is straight binary from MP1 input port; default after reset
input data is twos complement from MP2 input port (RGB path)
input data is straight binary from MP2 input port; default after reset
If VBSEN0 = 0, CVBS output signal is switched to CVBS DAC.
If VBSEN0 = 1, luminance output signal is switched to CVBS DAC; default after reset.
advanced composite sync is switched to CVBS DAC
Y, Cb and Cr for RGB dematrix is active; default after reset
Y, Cb and Cr for RGB dematrix is bypassed
horizontal and vertical trigger is taken from RCV2 and RCV1 respectively; default after reset
horizontal and vertical trigger is decoded out of “CCIR 656” compatible data at MP port
data from input ports is encoded; default after reset
colour bar with fixed colours is encoded
MP1 data is sampled on the rising clock edge; default after reset
MP1 data is sampled on the falling clock edge
MP2 data is sampled on the rising clock edge; default after reset
MP2 data is sampled on the falling clock edge
If SYMP = 1, horizontal and vertical trigger is decoded out of “CCIR 656” compatible data at
MP2 port; default after reset.
If SYMP = 1, horizontal and vertical trigger is decoded out of “CCIR 656” compatible data at
MP1 port.
video programming system data insertion is disabled; default after reset
video programming system data insertion in line 16 is enabled
