It integrates a high quality 2D comb Analog Video Decoder NTSC/PAL/SECAM video decoder, triple high speed RGB ADCs, NTSC (M, 4.43) and PAL (B, D, G, H, I, M, N, N combination), high quality scaler, versatile OSD and high performance MCU. PAL (60), SECAM with automatic format detection Its image video processing capability includes arbitrary Three 10-bit ADCs and analog clamping circuit. scaling, panoramic scaling, image mirroring, image adjustment and enhancement, black and white stretch, etc. On Fully programmable static gain or automatic gain control for the input side, it supports a rich combination of CVBS, S-video, the Y or CVBS channel component video, analog RGB as well as digital YCbCr/RGB Programmable white peak control for the Y or CVBS channel inputs. On the output side, it supports a variety of digital panel Software selectable analog inputs allow composite, S-video, types with its built-in timing controller. The integration of analog YPbPr or RGB additional touch screen controller, LED driver controller, PWM and MCU makes this a versatile solution for many portable High quality adaptive 2D comb filter for both NTSC and PAL applications. inputs PAL delay line for color phase error correction Applications Image enhancement with 2D dynamic peaking and CTI In-car display Digital subcarrier PLL for accurate color decoding Portable DVD and DVR players Digital horizontal PLL and advanced synchronization Portable media players processing for VCR playback and weak signal performance Programmable hue, brightness, saturation, contrast, sharpness High quality horizontal and vertical filtered down scaling with arbitrary scale down ratio SPI FLAT PANEL OUT SPI YIN0~2 MCU OSD TCON SIGNALS 2D-COMB CIN0~1 TCON SERIAL DATA VIDEO DECODER FONT OSD VIN0~1 BT.656 OUTPUT LED/ INPUT VCOM CONTROLLER CONTROL TRIPLE SCALER/ ADCs OUTPUT IMAGE FORMATTER DTVCLK ENHANCE 2-WIRE DTVHS, VS I2C SDAT SERIAL DTV BUS I/F DTVDE I2C SCLK DTVD 23:0 FIGURE 1.
