It integrates a high Built-in line locked PLL with sync separator quality 2D comb NTSC/PAL/SECAM video decoder, Support analog input resolution up to 1080i or triple high speed RGB ADCs, high quality scaler, and WXGA images enhancement functions, which include Black and White Stretch, etc. It also supports panoramic Digital Inputs Support scaling for conversion to wide screen display. On the Support 656 video formats input side, it supports a rich combination of CVBS, S- video, analog RGB as well as digital inputs. On the TFT Panel Support output side, it supports a variety of digital panel types with its built-in timing controller. Built-in programmable timing controller Supports 3, 4, 6 or 8 bits per pixel up to 16.8 million colors with built-in dithering engine Applications Support digital panel up to WVGA/SVGA resolution In-car display controller Support Serial (8-bit) RGB panel Portable DVD and DVRs players On Screen Display Portable media player 256 programmable font RAM and 384 display RAM Features Four windows font OSD with bordering / shadow Analog Video Decoder Supports bit-mapped based OSD through SPI (TW8832S only) NTSC (M, 4.34) and PAL (B, D, G, H, I, M, N, N combination), PAL (60), SECAM with automatic Image Processing format detection High quality scaler with both up/down and Three 10-bit ADCs and analog clamping circuit nonlinear scaling support Fully programmable static gain or automatic gain Built-in 2D de-interlacing function control for the Y or CVBS channel Programmable hue, brightness, saturation, contrast Programmable white peak control for the Y or CVBS and sharpness channel Supports programmable cropping of input video Software selectable analog inputs and graphics High quality adaptive 2D comb filter for both NTSC Independent RGB gain and offset controls and PAL inputs Panorama/Water-glass scaling PAL delay line for color phase error correction Programmable 10-bit Gamma correction for each Image enhancement with 2D dynamic peaking and color CTI Operated in Frame Sync mode Digital sub-carrier PLL for accurate color decoding Black/White Stretch Digital horizontal PLL and Advanced synchronization processing for VCR playback and weak signal performance Programmable hue, brightness, saturation, contrast and sharpness High quality horizontal and vertical filtered down scaling with arbitrary scale down ratio FN7855 Rev. 4.00 Page 1 of 3 May 6, 2014 TW8832, TW8832S Clock Generation Spread spectrum clock Modulation frequency and spread width are selectable Power Management Supports functional based independent power down 1.8/3.3 V operation Miscellaneous Supports 2-wire serial bus interface Built-in single LED back light controller Built-in VCOM DC voltage Built-in VCOM analog amplitude Built-in DC-DC convertor Single 27MHz crystal 80-pin LQFP package SPI Flat Panel Out YIN0~2 2D-Comb SPI OSD TCON signals TCON Video Font Decoder OSD CIN Serial Data Input LED/ Controller VIN VCOM Output Triple Control Triple Triple ADCs Formatter ADCs ADCs Scaler I2C SDAT Image 2-Wire DTVCLK Enhance Serial I2C SCLK Bus BT656 DTVD 7:0 I/F FIGURE 1.
