Product speciﬁcation

Digital servo processor (DSIC2)

TDA1301T

– 28-pin SO package

FEATURES

– Great flexibility towards different CD mechanisms

– Full and transparent application information

• High robustness/shock insensitivity

– Sophisticated track-loss (TL) detection mechanism

– Fast focus restart procedure

The DSIC2 realizes the following servo functions:

• Diode signal preprocessing

• Focus servo loop

• Radial servo loop

• Sledge motor servo loop

– Extended radial error signal

• Three-line serial interface via the microcontroller

– Adjustable radial shock detector

The other features include:

– Defect drop-out detector

• Full digital signal processing

• Low power consumption, down to 30 mW

• Low voltage supply 3 to 5.5 V

• Fully automatic jump procedure for radial servo

• Automatic focus start-up procedure and built-in FOK

(Focus OK)

• Integrated analog-to-digital converters and digital servo

loop filters

• Fast radial jump or access procedure

• Self-operational servo-control without continuous

communication via the microcontroller

• Double speed possible

• Easy application

• Direct communication to photodiode optics; no external

preprocessing.

– Single supply voltage

– Small number of external components; only

6 decoupling capacitors

GENERAL DESCRIPTION

– Flexible system oscillator circuitry

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.

– Usable for single/double Foucault and astigmatic

focus

– Full automatic radial error signal initialization offset

control and level initialization for track position

indicator

– No external adjustments required; no component

ageing

– Wide range of adjustable servo characteristics

– Simple 3-line serial command interface
