System LSI for CD player
BU9354KV
BU9354KV
BU9354KV is system LSI for CD player that integrates pre-servo amplifier, signal processing, RAM control for anti-shock
and D/A converter for audio into a single chip. Built-in programmable sequencer controller enables to construct optional
servo algorithm and servo filter.
!Applications
Portable CD player
!Features
1) Low power consumption design considering operation
by using RAM controller.
2) Programmable structure including servo filter.
3) Built-inx4 speed CMOS structure RF block and signal
processing circuit.
4) Built-in RAM controller for 4M, 16M DRAM.
5) MP3 decoder connectable.
