General Description
Bt869 General Description
The Bt868/869 is specifically designed for video systems requiring the generation of high-quality flicker-free composite and Y/C (S-video) signals from various YCrCb or RGB digital streams. The Bt868/869 accepts any input format from 640 x 480 to 800 x 600 resolution.
The Bt868/869 uses Conexant's UltraScale™ technology to provide the most advanced vertical and horizontal scaling necessary for the display of non-interlaced data on interlaced devices such as the TV. The UltraScale™ technology converts the lines of input pixel data to the appropriate number of output lines for producing a full-screen, high-quality image.
The Bt868/869 performs 5-line vertical filtering, which includes poly phase interpolation scaling for overscan compensation and flicker filtering. Horizontal scaling for overscan compensation is achieved by altering the encoder clock frequency. This approach preserves all of the high frequency components of the input signals, which are essential for the highest quality display of text intensive images such as web pages on TVs. The amount of flicker filtering and overscan compensation is programmable.
Worldwide video standards are supported, including NTSC-M (N. America, Taiwan, Japan), PAL-B,D,G,H,I (Europe, Asia), PAL-M (Brazil), PAL-N (Uruguay, Paraguay), and PAL-Nc (Argentina). Bt868 and Bt869 are functionally identical, with the exception that Bt869 can output Macrovision Level 7.0 anticopy algorithm.

(1)This device employs high-impedance CMOS devices on all signal pins. It should be handled as an ESD-sensitive device. Voltage on any signal pin that exceeds the power supply or ground voltage by more than 0.5 V can cause destructive latchup.
Stresses above those listed under "Absolute Maximum Ratings" can cause permanent damage to the device. This is a stress rating only, and functional operation of the device at these or any other conditions above those listed in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods can affect device reliability.
