ADV7194: Professional Extended-10™ Video Encoder with 54 MHz Oversampling
製品概要
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.
