Description

The TDA1301T is a fully digital servo processor which has been designed to provide all servo functions, except the spindle motor control, in two-stage three-spot compact disc systems. The device offers a high degree of integration, combined with the low additional cost of external components. The servo characteristics have a wide range of adjustment via a three-line serial interface. This offers an enormous flexibility with respect to applications for different CD mechanisms. The circuit is optimized for low-power low-voltage applications.
