DESCRIPTION
The Visba™ 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.
