HDMI Video Output
[
, callout
The VC707 board provides a High-Definition Multimedia Interface (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 and RGB video modes through 36-bit input data
mapping.
The VC707 board supports the following HDMI device interfaces:
•
36 data lines
•
Independent VSYNC, HSYNC
•
Single-ended input CLK
•
Interrupt Out Pin to FPGA
•
