The ADV7194 is part of the new generation of video encoders from Analog Devices.

The ADV7194 is an integrated Digital Video Encoder that converts Digital CCIR-601 4:2:2 Component Video Data (8-, 10-, 16-, 20-bit) into a standard analog base band television signal compatible with NTSC, PAL B/D/G/H/I, PAL N& PAL-60. In addition to the composite output signal, there is the facility to output S-VHS Y/C Video, RGB Video and YUV Video. The Y/C, RGB and YUV format is simultaneously available at the analog outputs with the composite video signal. The ADV7194 combines 10-bit conversion, 10-bit digital video data processing and 10-bit external interfacing (Extended-10™). All six DACs are capable of providing an output current of 4.33 mA. The ADV7194 also supports both a PAL and NTSC square pixel modes.

The ADV7194 incorporates in its new design programmable Gamma Correction, programmable Digital Noise Reduction and 4x Oversampling with an internal PLL to output data at 54 MHz. Furthermore, it is possible to input data in progressive scan format (3x10-bit YCrCb).

Video control functions have been improved in increasing scale factors for the color and contrast controls and the brightness control. An Average Brightness Detection control has been added as well as a Field Counter. Also, Chroma and Luma can now individually be delayed if required.

All internal clocks are generated on-chip. The ADV7194 modes are set up over a serial bi-directional I²C port. Additionally, the ADV7194 allows a sub-carrier phase lock with an external video source and has a color bar generator on-board.

The ADV7194 is designed with programmable Luminance and Chrominance filters for better video performance. The Luminance filter has a special mode called SSAF™, which gives extended bandwidth and has a very sharp roll-off.

The ADV7194 is designed with four color controls (Hue, Contrast, Brightness and Saturation).

There is also the facility to boost the Luminance signal in changing the response of the SSAF™ filter.

HSO & VSO/CSO TTL O/P's timed to the analog output video are available.

A CLAMP output signal is available to enable clamping in both the Front and Back Porch of the video signal.

All YUV formats (BetaCam, MII and SMPTE/EBU N10) are supported.

The ADV7194 also has a separate teletext input port.

The ADV7194 has an Advanced Power Management system whereby the Sleep current is lower than 1mA and still allows I²C access during this Sleep Mode of operation. This is ideal for portable equipment which is sensitive to power consumption like Laptops.

The ADV7194 is fabricated in a +3 V CMOS process. Its monolithic CMOS construction ensures greater functionality with low power dissipation. The ADV7194 is packaged in a 80-Pin LQFP package.

The model number is a specific version of a generic that can be purchased or sampled.

Status indicates the current lifecycle of the product. This can be one of 4 stages:

• Pre-Release: The model has not been released to general production, but samples may be available.
• Production: The model is currently being produced, and generally available for purchase and sampling.
• Last Time Buy: The model has been scheduled for obsolescence, but may still be purchased for a limited time.
• Obsolete: The specific part is obsolete and no longer available. Other models listed in the table may still be available (if they have a status that is not obsolete).
