Part 10: HDMI Output Interface
The implementation of HDMI output interface is ADALOG DEVICE's
ADV7511 HDMI (DVI) encoding chip, which supports 1080P@60Hz output and
supports 3D output.
Among them, the ADV7511's video digital interface, audio digital interface
and I2C configuration interface are connected with the BANK35 IO of the
ZYNQ7000 PL part. The ZYNQ7000 system initializes and controls the
ADV7511 through the I2C pin. The hardware connection diagram of ADV7511
chip and ZYNQ7000 is shown in Figure 10-1.
