The authors have developed 12 custom semiconductor devices for a compact disc digital audio player (4 LSIs, 7 Ics and 1 DAC). The MN6611, 6613 LSIs for digital signal processing perform EFM decoding, control and display decoding, and CIRC error correction in the highest grade of error correction and detection. The MN6610 LSI is used for CLV system control. The AN7670, 7671, 7672, 7673, 7674, 7675 and 7676 Ics are designed for optical head servo control, random trick access and optical deck drive control. The AN6806 16-bit one-chip DAC has the highest grade of linearity (+/-0.002%) and a settling time of 0.4us.
