01W136A Signal processor LSI with anti-shock memory controller for CD players BU9534KV Dimension (Units : mm) 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. 16.0 ± 0.2 14.0 ± 0.1 51 75 76 Features 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 26 1.0 1.4 ± 0.05 0.1 ± 0.05 1.6Max. 100 1 0.5 ± 0.15 1.0 ± 0.2 16.0 ± 0.2 14.0 ± 0.1 50 1.0 Description 25 0.5 ± 0.1 +0.05 0.2 -0.04 0.145 +0.05 -0.03 4°+6° -4° 0.08 S 0.08 M VQFP100 Applications Portable CD players Absolute Maximum Ratings (Ta=25°C) Parameter Symbol Limits Unit Vcc 4.5 V Maximum applied voltage Power dissipation 1000 * Pd Operating temperature range Topr –25 Storage temperature range Tstg –55 ~ ~ 75 125 mW °C °C *Derating : 10mW/°C for operation above Ta=25°C February, 2002 Recommended Operating Conditions (Ta=25°C) Parameter Operating power supply voltage Symbol Min.
