Part 9: HDMI1 Output interface
The implementation of the HDMI output interface on the AX7035
development board is to directly connect the differential signal and clock of the
HDMI interface through the differential IO of the FPGA, realize the differential
output of the HMDI signal after the data is encoded and parallel-to-differentially
converted in the FPGA, and realize the HDMI digital video. The output
transmission solution supports up to 1080P@60Hz output.
The differential drive signal of HDMI passes through the IO output of FPGA
BANK35, and the ESD protection device is added to the signal interface. In
addition, the HPD (hot plug detect) signal is used to detect whether the external
HDMI display device is inserted. Figure 9-1 is detailed the HDMI output
