LSI Computer Systems BU9532KS2

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.
