DESCRIPTION
The VisbaTM ES3889 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 ES3889 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, cost-effective design for a video CD player. The Visba video CD CC provides the best quality for both video and audio. The Visba video CD CC features include a high-quality NTSC/ PAL digital video encoder (DVE), echo, surround sound, audio DACs, and a phase-locked loop (PLL) clock synthesizer. Additionally, there are 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. Figure 1 shows a block diagram of a typical standalone system, using the Visba ES3880 video CD processor chip and a Visba ES3889 video CD CC.
