DATASHEET TW2867C FN8257 Rev. 0.00 4-Channel Video Decoders and Audio Codecs For February 9, 2012 Security Applications Programmable audio sample rate that covers The TW2867 includes four high quality popular frequencies of 8/16/32/44.1/48kHz NTSC/PAL/SECAM video decoders that convert Supports a two-wire serial host interface analog composite video signal to digital component YCbCr data for security applications. Integrated clock PLL for 108MHz clock output. Each channel contains 10 bit ADC and proprietary Ultra low power consumption (Typical clamp and gain controllers and utilizes 4H comb 431.88mW) filter for separating luminance & chrominance to 128 pin LQFP package reduce cross noise artifacts. The TW2867 adopts the image enhancement techniques, such as IF compensation filter, CTI and programmable peaking. The TW2867 also includes audio CODEC, which has five audio Analog-to-Digital converters and one Digital-to-Analog converter. A built-in audio controller can generate digital outputs for recording/mixing and accepts digital input for playback. Features Accepts all NTSC(M/4.43) / PAL(B/D/G/H/I/K/L/M/N/60)/SECAM standards with auto detection Integrated four video analog anti-aliasing filters and 10 bit CMOS ADCs High performance adaptive 4H comb filters for all NTSC/PAL standards IF compensation filter for improvement of color demodulation Color Transient Improvement (CTI) Automatic white peak control Programmable hue, saturation, contrast, brightness and sharpness Proprietary fast video locking system for non- realtime application Supports the standard ITU-R BT.656 format or time multiplexed output with 54/108MHz Provides simultaneous four channel Full D1 and CIF time-multiplexed outputs with 54MHz. Integrated five audio ADCs and one audio DAC Provides multi-channel audio mixed analog output Supports I2S/DSP Master/Slave interface for record output and playback input PCM 8/16 bit and u-Law/A-Law 8bit for audio word length FN8257 Rev. 0.00 Page 1 of 138 February 9, 2012 TW2867C Block Diagram VIN1A VD1 7:0 44HH CCoommbb ADC ADC VViiddeeoo DDeeccooddeerr VD2 7:0 VIN1B VD3 7:0 AIN1 AADDCC DDeecciimmaattiioonn FFiilltteerr VD4 7:0 MPP1 VIN2A MPP2 44HH CCoommbb AADDCC VViiddeeoo DDeeccooddeerr MPP3 VIN2B MPP4 AIN2 AADDCC DDeecciimmaattiioonn FFiilltteerr CLKPOn XTO VIN3A XTI 44HH CCoommbb AADDCC VViiddeeoo DDeeccooddeerr CLKNOn VIN3B SCLK AIN3 ADC ADC DDeecciimmaattiioonn FFiilltteerr SDAT IRQ VIN4A 44HH CCoommbb ADC ADC ACLKR VViiddeeoo DDeeccooddeerr VIN4B ASYNR ADATR AIN4 ADC Decimation Filter ADC ADATM ACLKP ASYNP AIN5 Decimation Filter ADC ADATP DAC AOUT Interpolation Filter Ordering Information PKG.
