DATASHEET TW2866C FN8253 Rev. 0.00 4-Channel Video Decoders and Audio Codecs and February 3, 2012 Video Encoder for Security Application Provides multi-channel audio mixed analog The TW2866 includes four high quality output NTSC/PAL/SECAM video decoders that convert analog composite video signal to digital Supports I2S/DSP Master/Slave interface for component YCbCr data for security applications. record output and playback input Each channel contains 10 bit ADC and proprietary clamp and gain controllers and PCM 8/16 bit and u-Law/A-Law 8bit for audio utilizes 4H comb filter for separating luminance word length & chrominance to reduce cross noise artifacts. Programmable audio sample rate that covers The TW2866 adopts the image enhancement popular frequencies of 8/16/32/44.1/48kHz techniques, such as IF compensation filter, CTI and programmable peaking. TW2866 also Supports a two-wire serial host interface includes one NTSC/PAL video encoder with two Integrated one video encoder and two10 bit 10 bit DACs to support CVBS and YC output. The video CMOS DACs. TW2866 also includes audio CODEC, which has five audio Analog-to-Digital converters and one Integrated clock PLL for 108MHz clock output. Digital-to-Analog converter. A built-in audio controller can generate digital outputs for Ultra low power consumption (Typical recording/mixing and accepts digital input for 666.84mW) playback. 128 pin LQFP package 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.
