Color Space Conversion
Although all processing in the
is performed in the YCbCr color space, the part is capable of receiving video in the RGB, YUV and
provides any-to-any CSC on each of the inputs and on both of the outputs (five color space converters in
all). All CSCs support formats such as RGB, YUV and YCbCr. The front end CSCs on the primary input channel, secondary input channel and
RX input channel run at a maximum clock rate of 162 MHz. The back end CSCs in HDMI Tx1 and HDMI Tx2 operate at a maximum input
clock rate of 300 MHz.
2.2.12.1.
Primary Input Channel CSC
The CSC must be manually configured for each color space conversion. The CSC on the primary input channel can be enabled using the
control. This CSC can run at 297 MHz and provides color space conversion for UHD video formats. The CSC mode on the
primary input channel can be configured using
. The CSC mode is used to define the fixed point position of the CSC
coefficients which are located after
in the IO Map for the primary input channel.
Reference configuration scripts to configure the primary input channel CSC are provided with the evaluation software.
