SC9827
VCD SIGNAL-CHIP PROCESSOR
DESCRIPTION
SC9827 is a single chip SOC for CD-G system, it integrates CD
servo and correct decoder, Audio DAC. Working with the RF pre-
processor of CD composes a low cost and high performance CD-G
system solution.
FEATURES
* Periphery circuit is simple, servo and decoder integrated;
* Support CD-G decode play;
* Embedded Audio DAC, PWM output;
* JPEG decode and play function;
* OSD function;
* Adopts CD servo arithmetic, strong correct function and good
coherence.
APPLICATION
* CD-G system
LQFP-128-14X14-0.4
