RENESAS TW2866-LC1-CR

The TW2866 includes four high quality NTSC/PAL/SECAM video decoders that convert analog composite video signal to digital component YCbCr data for security applications. Each channel contains 10 bit ADC and proprietary clamp and gain controllers and utilizes 4H comb filter for separating luminance & chrominance to reduce cross noise artifacts. The TW2866 adopts the image enhancement techniques, such as IF compensation filter, CTI and programmable peaking. TW2866 also includes one NTSC/PAL video encoder with two 10 bit DAC’s to support CVBS and YC output. The TW2866 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.
