User-customizable Presets
The EVD application also includes a mechanism whereby parameter settings as defined on the slider
panel may be stored into the three presets on the Demonstrator board, for later use with the board in
stand-alone mode (without USB connection). This allows a customer to configure the board with
enhancement capability of their own choosing, tailored for a specific application, and then, for
example, send it out for operation in the field in compact form without the need for additional ancillary
equipment. The customizable preset capability on the Demonstrator boards can also be accessed
directly via the USB interface. The use of these features is also described in detail in an additional
Application Note.
Circuit Implementation
The block diagram below is representative of the Demonstrator board, and also provides a simple
example application for use in other existing systems. It shows all of the possible major commonly
used inputs/outputs of the EVD1000, but highlights the very simple basic connections required for
operation in this mode.
Here, video input and output for the EVD1000 is shown as YCrCb 4:2:2 digital data with embedded
SAV and EAV codes (hence the use of blanking/sync inputs/outputs are not required). The standard
receiver and transmitter handle the conversion to/from HDMI/DVI video signals which are in this case
external to the board. Note that in this mode, the video data clock for all components on the board is
derived from the input data stream by the HDMI receive r. As can be seen from the diagram, this is a
particularly simple and easy-to-implement connection scheme, although the use of the EVD1000 with
