The TW2864 contains four Automatic white peak control 10-bit ADC and proprietary clamp and gain controllers Programmable hue, saturation, contrast, brightness and utilizes 4H comb filter for separating luminance and and sharpness chrominance to reduce cross noise artifacts. The Proprietary fast video locking system for non-realtime TW2864 adopts the image enhancement techniques, applications such as IF compensation filter, CTI and programmable peaking. The TW2864 also includes audio CODEC, which Supports the standard ITU-R BT.656 format or time has four audio Analog-to-Digital converters and one multiplexed output with 54/108MHz Digital-to-Analog converter. A built-in audio controller Provides simultaneous four channel Full D1 and CIF can generate digital outputs for recording/mixing and time-multiplexed outputs with 54MHz accepts digital input for playback. Integrated four audio ADCs and one audio DAC Provides multi-channel audio mixed analog output Features Supports I2S/DSP Master/Slave interface for record Accepts all NTSC(M/4.43) / output and playback input PAL(B/D/G/H/I/K/L/M/N/60)/SECAM standards with PCM 8/16-bit and u-Law/A-Law 8-bit for audio word auto detection length Integrated four video analog anti-aliasing filters and Programmable audio sample rate that covers popular 10-bit CMOS ADCs frequencies of 8/16/32/44.1/48kHz High performance adaptive 4H comb filters for all Supports a two-wire serial host interface NTSC/PAL standards Ultra low power consumption (Typical 388.5mW) 100 pin LQFP package FN7745 Rev. 0.00 Page 1 of 110 September 28, 2012 TW2864 Device Type PRODUCT AUDIO DEFAULT TYPE FEATURES CLOCK RATE TW2864A 108MHz TW2864B 54MHz TW2864C N/A 108MHz TW2864D N/A 54MHz Block Diagram VD1 7:0 4H Comb VIN1 ADC Video Decoder VD2 7:0 VD3 7:0 AIN1 ADC Decimation Filter VD4 7:0 MPP1 MPP2 4H Comb VIN2 ADC Video Decoder MPP3 MPP4 ADC Decimation Filter AIN2 CLKPO CLKI 4H Comb VIN3 ADC CLKNO Video Decoder SCLK AIN3 ADC Decimation Filter SDAT IRQ 4H Comb VIN4 ADC ACLKR Video Decoder ASYNR ADATR AIN4 ADC Decimation Filter ADATM ACLKP ASYNP AOUT DAC Interpolation Filter ADATP FN7745 Rev. 0.00 Page 2 of 110 September 28, 2012 I2S Host Clock MPP BT.656 Interface Interface Generator Interface Interface
