Secondary Input Channel
The
secondary input channel incorporates an input formatter, CSC and updither block.
The input formatter provides a number of controls to configure what data the secondary input channel is configured for. The secondary input
channel must be connected to either the video TTL input pins or the EXOSD TTL input pins using
channel is connected to the video TTL input pins, the format and bit width of the data, for example, 2 x 8 bit buses of 4:2:2 data, must be specified
using
can be used to indicate which input pins are used to carry the upper, middle and lower
ranges of bits (for example, upper = D[35:25], middle = D[24:12], lower = D[11:0]; or upper = D[11:0], middle = D[35:25], lower = D[24:12]).
