Description
The Q888 is a Digital Servo Integrated Circuit Silent (DSICS) IC that provides all servo functions except the spindle motor control in two-stage Compact Disc (CD) systems. It offers a high degree of integration, combined with the low additional cost of external components. The servo characteristics are widely adjustable by means of a three-wire serial interface, which offers great flexibility for the application of different CD mechanisms.
