CXD2545Q and newer have an internal servo controller and only need an external RF-amp (CXA2550N up to PU-20 or CXA2575N from PU-22 and later). For driving the sled motor, spindle motor, tracking coils and focus coils, each PlayStation also has a driver IC for this purpose with its signal inputs connected to the DSP. | ||
