TDA9989
HDMI 1.3a transmitter with CEC support
The TDA9989 can accept any of the following video input modes (see Table 6):
• RGB, with 8-bit for each component
• YCbCr 4 : 4 : 4, with 8-bit for each component
• YCbCr 4 : 2 : 2 semi-planar, with up to 12-bit for each component (YCbCr)
• YCbCr 4 : 2 : 2 ITU656, with up to 12-bit data depth
The TDA9989 can be set to latch data at either rising or falling edge, or both.
7.2.2 Internal assignment
The aim of the video input processor is to internally map the incoming data to the
corresponding mode, which can be handled by the video processing. The internal signal
named VP[23:0] is assigned depending on the input mode as defined below.
