三、CL680解码芯片 1.CL680的基本特性 CL680解码芯片是继CL480和CL484之后C-Cube公司新开发的VCD解码芯片。CL680除了具有CL480/CL484所有的基本功能之外又增加了一些新的功能。CL680的CD-ROM解码、MPEG1音频、视频解码、高分辨力静像解码等数据处理功能均与CL480/484相同。此外,CL680还增加了数字NTSC/PAL编码器和音频卡拉OK处理电路,而且还提高了集成度,简化了外围电路。 CL680采用了先进的数字信号处理(DSP)技术,可将光盘上的标准立体声和环绕声的音场展宽。它还可将单声道
Third, the CL680 decoder chip 1.CL680 the basic characteristics CL680 decoder chip is CL480 and CL484 C-Cube’s newly developed VCD decoder chip. CL680 addition to CL480 / CL484 all the basic features and added some new features. CL680 CD-ROM decoding, MPEG1 audio, video decoding, high resolution still image decoding and other data processing functions are the same with the CL480 / 484. In addition, CL680 also added digital NTSC / PAL encoder and audio karaoke processing circuit, but also increased the integration, simplifying the peripheral circuits. The CL680 incorporates advanced digital signal processing (DSP) technology to stretch the standard stereo and surround sound fields on the disc. It can also be mono
