Video Interface Support
The VIODC supports the following video interfaces:
•
LVDS Camera Input Port
– The LVDS camera input port supports the Irvine Sensors
LVDS RGB camera with a Micron MT9V022 1/3 inch CMOS image sensor. The camera
provides 752 x 480 pixels at 60 Hz progressive scan. It features low noise and very
high dynamic range. The interface is implemented using LVDS signaling over
standard Cat-6 Ethernet cables. Note that the LVDS camera interface is not compatible
with Ethernet.
•
S-Video and Composite Video
– The VSK supports S-Video inputs and outputs.
These interfaces can be configured to support NTSC, PAL, and virtually any other SD
video format. The S-video input interface is supported by the ADV7403 decoder IC
and output by the ADV7321 encoder IC. In addition to the encoder and decoder,
analog filters are used to limit the video bandwidth.
•
Component Video I/O
– The component video I/O use standard RCA connectors to
provide HD video the VSK. Component video is encoded as YPbPr video channels.
The component video input on the supports 1080I, 720P, and 525P video standards.
The Component video interface devices on the VSK support 10-bit digital video.
Component video input is supported by the ADV7403 IC decoder IC and output by
the ADV7321 encoder IC and analog filter sections.
•
DVI Digital Video I/O
– The VSK supports DVI video inputs and outputs. DVI is
commonly used to interface to flat panel displays and computer graphics cards. The
VSK DVI interfaces supports up to a pixel clock of up to 165 MHz. In addition to
computer graphics, DVI is also used to carry HD video and is commonly found in
high-end consumer video equipment, such as plasma displays, and can be found on
some DVD players. The DVI ports can also be connected to HDMI interfaces by using
a DVI/HDMI adapter. A TP410 IC is used to support DVI output and an AD9887 IC
provides DVI input.
•
VGA Interface
– VGA input and outputs are is available on the VIODC card. The
VGA output is routed to the analog output pins of the DVI output connector. It is
sourced by an ADV7123 10-bit DAC. VGA input is captured by the AD9887 IC.
