scheme, although the use of the EVD1000 with other data formats and synchronization structures is
of course possible as well, with not much greater complexity required.
In the present case, the EVD1000 is controlled via an industry-standard two-wire serial configuration
bus (SCL, SDA), along with the video decoder and encoder. Power-up initialization, mode selection,
and all enhancement parameter selection is accomplished using this mechanism. The
microcontroller also handles the simple example user interface in this design.
As described in an Application Note (and the data sheet), it is possible to operate the EVD1000
without a microcontroller for an even simpler circuit design, through the use of suitably chosen
dedicated EVD1000 pins, pull-up resistors, etc. for mode and format control and basic enhancement
level selection. But in any applications (such as this example) which already include a microcontroller
with serial configuration bus capability for other purposes in the customer’s system design, complete
control over all of the enhancement modes, parameter registers, and other advanced features is
readily available with no additional components or hardware effort.
A more detailed schematic for the analog Demonstrator board is also available from EVD. The
presently shown application and a number of other connection methods are described in more detail
in a series of Application Notes as well as in the data sheet.
Conclusion
As can be seen, circuit implementation for integration of the EVD1000 series chips in a customer
design is very straightforward. Familiarization with the operation and selection of enhancement
parameters for various applications is facilitated by the use of the Demonstrator board, and software
development can occur in parallel to customer board design and construction. Numerous application
and design aids are available from EVD to help guide all phases of the process.
