VisbaTM ES3883
Video CD Companion Chip
ESS Technology, Inc.
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.
