TW2865-LA3-GR - 4-Channel Video Decoder and Audio Codec plus Video Encoder for Security Applications - Intersil Corporation
The TW2865 is a 4-in-1 video decoder and audio codec plus video encoder for security surveillance applications. The device includes four high
quality NTSC/PAL/SECAM video decoders that convert analog composite video signal to digital component YCbCr data. Each channel contains a
10-bit ADC and proprietary clamp/gain controller and utilizes 4H comb filter for separating luminance & chrominance to reduce cross noise
artifacts. The TW2865 adopts image enhancement techniques such as IF compensation filter, CTI and programmable peaking. In addition,
TW2865 includes one NTSC/PAL video encoder with two 10-bit DACs to support CVBS and YC output. The TW2865 also includes an audio codec
which has five audio ADCs and one DAC. A built-in audio controller can generate digital outputs for recording/mixing and accepts digital input
for playback.
