This chapter describes the DVI and VGA input interface theory of operation. It covers the
signals and presents an overview of the internal operating modes of the AD9887. Users can
refer to the
The VIODC DVI/VGA input interface allows standard PC video formats to be captured.
This includes analog VGA formats and digital DVI up to 1600x1200 at 60 Hz.
The DVI/VGA input portion of the video input and output daughter card (VIODC) has
two connectors. The first is a traditional HD15 as used by all older analog video cards and
monitors. The second connector is a DVI-I connector which includes pins for both the
analog VGA interface and the DVI digital interface. Note that the analog pins of the two
connectors are tied together, so that only one or the other can be used at any time. See

VIODC uses Analog Devices
includes two very separate subsections: the analog (VGA) interface and the digital (DVI)
interface. Via the I2C control bus, this part can be configured to receive either of the modes
and output it in a parallel digital form to the FPGA.
The AD9887A interface has a parallel digital bus interface to the FPGA for video data and
an I2C control bus for configuration.
