Signal processor LSI with pre-servo amplifier for CD players
BU9532KS2
Description
BU9532KS2 is a digital signal processor LSI with
built-in pre-servo amplifier developed for CD players.
This built-in pre-servo amplifier is applied to the RW
functions of the compact disc. Combining ROHM's
BU24393 – a system micro controller with this new DSP
BU9532KS2 provides an extremely simplified CD system.
