Portable CD players
BU9534KV is a digital signal processor LSI with built-in
pre-servo amplifier, and anti-shock memory controller
developed for CD players. This pre-servo amplifier is
applied to CD-RW disc. Approximately 180sec. music
data can be stored in memory by connecting with 64M
bit SDRAM.
Signal processor LSI with anti-shock memory controller for CD players
1) Anti-shock memory controller corresponds to EDRAM,
and SDRAM. Maximum 180sec. of music data can be
stored by using 4bit compression mode and 64bit SDRAM.
2) Built-in pre-servo amplifier for playing CD-RW
3) Tracking, Focus automatic control
4) Built-in wide PLL, CLV
5) Symmetry correction function
6) Built-in x8 over sampling filter + 1bit DAC
7) Digital bass boost, soft mute function
