CL680 VIDEO-CD DECODER
SINGLE-CHIP AUDIO/VIDEO/CD-ROM DECODER WITH INTEGRATED
NTSC/PAL ENCODER
The CL680 VideoCD Decoder is a highly integrated MPEG-1 system decoder for VideoCD
players.
• Higher Integration: The CL680 has an integrated digital NTSC/PAL encoder, eliminating
the need for a discrete device and reducing total design footprint. Stereo key control and
vocal fade features replace additional audio circuitry in Karaoke applications. No other
single-chip decoder on the market can match the CL680’s level of integration.
• Enhanced Quality: The CL680 incorporates WideSound™, C-Cube’s proprietary audio
technology that provides a surround sound experience in stereo applications. Also, the
OSD feature has been enhanced to display more on-screen characters.
• Greater Reliability: C-Cube’s ClearView™ technology, introduced on the CL484, has been
further enhanced in the CL680. VideoCD players based on the CL680 play more types of
media and have fewer visible flaws than ever.
The CL680’s microcoded architecture enables OEMs to retain their engineering investment
in hardware and system software from their CL484 designs. CL680-based designs can be
upgraded to add new features as the CL680 product line evolves without changing the
hardware design.
