Analog Devices offers a diverse range of products to complete the advanced TV signal chain, including multiformat video decoders
(ADV7402), dual interface graphics and HDMI/DVI receiver products (AD9880
), video encoders (ADV7310), and video DACs
(ADV7123). Standard definition video decoders, including the ADV7183A, ADV7189, and ADV7181*, are also available for multichannel
configurations and other video recording and processing applications. The AD1991 Class D Audio Power Amplifier Output Stage also
enables state-of-the-art, compact electronic component design for home theater systems and flat-panel displays.

The ADV7402 and ADV7400 multiformat video
decoders simplify front end digitizer and decoder
architectures by reducing board space, simplifying
auto detection and switching of inputs, and
reducing overall system power consumption.
For TV configurations, the ADV7402/ADV7400
can process and switch between the following
signal types without the need for external
multiplexer circuitry:
RGB graphics outputs from a PC graphics card
YPbPr outputs from a progressive scan DVD
player or high definition set-top-box
Composite video from a TV tuner or VCR
S-Video from a camcorder or S-VHS VCR
Ideally suited to applications that require support
for all these inputs, the ADV7402/ADV7400 can
interface directly to many graphics controllers,
scalers, de-interlacers, MPEG encoders, and
image enhancement processors with bus widths
as low as 10 bits (+clock) for all scanning rates
and sampling schemes.

For more information on these products and
Analog Devices' extensive video and imaging
product portfolio, please visit our website.
Evaluation kits for the ADV7402 and ADV7400 are now available from Analog Devices. All kits include the equipment
necessary to start prototyping with those devices. With the on-board ADuC831 microcontroller, each kit comes ready
programmed for standalone operation, including pre-programmed auto detection and mode selection via the
on-board rotary hex switches.
Each video decoder module is equipped with standard RCA/Phono type connectors for component and composite
video inputs. A mini-Din connector is also provided for S-Video connections, along with a 15-Pin D-Sub for standard
RGB graphics inputs.
A display output module equipped with video encoder (ADV7310), graphics DAC (ADV7123), and DVI transmitter
provides a variety of output formats to interface with professional analog or digital displays and basic televisions.
Control software is provided for complete configuration of each module via the parallel port of a PC using serial
communications. Various add-on modules are also available to provide data bus expansion and support for future
functionality.
