, callout
The KC705 board provides a High-Definition Multimedia Interface (HDMI) video output
using the Analog Devices ADV7511KSTZ-P HDMI transmitter (U65). The HDMI output is
provided on a Molex 500254-1927 HDMI type-A connector (P6). The ADV7511 is wired to
support 1080P 60Hz, YCbCr 4:2:2 encoding via 16-bit input data mapping.
The KC705 board supports the following HDMI device interfaces:
•
18 data lines
•
Independent VSYNC, HSYNC
•
Single-ended input CLK
•
Interrupt Out Pin to FPGA
•
