DESCRIPTION

The Visba ES3883 video CD companion chip (CC) is the second-generation companion chip that provides an optimal system design for a video CD player when used with the Visba ES3880 video CD PC. The ES3883 Visba video CD CC integrates the CD-ROM controller (featuring direct servo control), as well as most of the required analog discrete components, into a simple, highly cost-effective design for a video CD player. The Visba video CD CC provides the best quality for both video and audio, and easily passes the highest graded level for the China VCD standard.

The Visba video CD CC features include a high-quality NTSC/ PAL digital video encoder (DVE), echo, surround sound, audio DACs, and PLL clock synthesizer. Additionally, there are also three 9-bit video DACs and two 16-bit sigma-delta audio DACs. One video DAC handles composite video output, while the other two handle the S-video outputs. The two 16-bit sigma-delta audio DACs offer differential outputs. The differential dual audio outputs from these audio DACs ensure further noise reduction to a minimum of 90 dB, enabling the Visba video CD CC to pass the best quality audio on all video CD parameter specifications.

The DVE generates composite and S-video analog signals. Color space conversions (CSCs) are provided to match the input data to the required output format. Then, the data is filtered to meet the selected video standards. In addition, the Visba video CD CC is equipped with a remote control interface for power standby on/off, two microphone ports, auxiliary ports, and an interface for accessing internal registers.

The ES3883 is available in an industry-standard 100-pin plastic quad flat pack (PQFP) package.
