HDMI Video Output
[Figure 1-2, callout 17]
The AC701 board provides a HDMI video output using the Analog Devices
ADV7511KSTZ-P HDMI transmitter (U48). The HDMI output is provided on a Molex
500254-1927 HDMI type-A connector (P2). The ADV7511 is wired to support 1080P 60
Hz,
YCbCr 4:4:4 encoding using 24-bit input data mapping.
The AC701 board supports the following HDMI device interfaces:
• 24 data lines
• Independent VSYNC, HSYNC
• Single-ended input CLK
• Interrupt Out Pin to FPGA
•I2C
•SPDIF
