Conexant CX25858 8路音视频译码方案
Conexant 公司的CX25858是集成了用作监视的PCIe接口的8路音视频译码器,包括有8路高质量的NTSC/PAL视频译码器和10位ADC以及5路梳状滤波器,可以获得最高质量数字视频输出和尽可能最低噪音. CX25858还包括8路高质量单声道音频A/D和I2S输出.本文介绍了CX25858主要特性,方框图,以及多路音/视频译码器评估板主要特性和方框图.
The CX25858 8-Channel Audio/Video Decoder with Integrated PCIe Interface was designed for surveillance applications. The CX25858 contains eight high quality NTSC/PAL video decoders with 10-bit A/Ds and 5-line comb filtering, to generate the highest quality digital video output with the lowest possible noise. This creates not only the best image quality for viewing, but enables lower bitrates for compression devices using the output of the CX25858.
The video decoders within the CX25858 are optimized to lock to inputs with low signal levels as well as line-locked cameras, both of which are common in surveillance systems. Each video decoder may be scaled independently and the CX25858 supports BT.656 as well as a variety of other interleaved digital video output formats.
The CX25858 also contains eight high-quality mono audio A/Ds with I2S outputs.
