OQ8868 General Description

The Digital Servo Integrated Circuit Silent (DSICS) IC 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.

The servo chip accepts diode currents and drives various power stages. Proper functioning of the focus and radial AGCs requires a digital power stage (SZA1010). It can drive normal, CDM12-like, mechanisms.

It is the improved version of its predecessor, the DSIC2 (TDA1301).

OQ8868 Maximum Ratings

SYMBOL PARAMETER MIN. MAX. UNIT

VSS ground supply voltage difference between VSSA and VSSD -5 +5 mV
Pdiss power dissipation - 200 mW
Tstg storage temperature 55 150  
Tamb operating ambient temperature -40 +85  
Vesd electrostatic handling -2000 +2000 V

OQ8868 Features

· Focus servo loop
· Radial servo loop
· Built-in access procedure
· Sledge motor servo loop
· Three line (TDA1301T-like; same on hardware level, coefficients differ) or I2C-bus serial interface with system controller. Other features are:
· Single supply voltage (5 V)
· Flexible system oscillator
· Usable for single/double Foucault and astigmatic focus
· Wide range of adjustable servo characteristics possible
· Automatic focus start-up procedure and in-lock indication
· Fast focus restart procedure
· Sophisticated track loss detection mechanism
· Extended radial error signal
· Automatic initialization and jump procedure for radial servo
· Automatic radial error gain and offset control
· Sophisticated defect detector
· Shock detector
· Fast serial communication
· Low noise servo loops
· Automatic gain control for the complete focus and radial loop
· Fast track counting signal input
· Steered sledge jump
· Radial actuator damping. Features that improve on its predecessor, the TDA1301T:
· Low noise in the focus loop
· Faster serial communication
· Improved jump performance. Added features are:
· High level watchdogs
· Decoder (LO9585, LO9588 or HD60) communication support
· Application debugging support
· Pulsed sledge mode
· Auto gain control on radial and focus loop
· I2C-bus serial communication
· Externally available defect detector signals.
