Overview

The LA9702W is an RF signal-processing and servo error

signal generation IC for DVD and CD playback. A DVD

player can be implemented by combining this IC with a

DVD DSP product that includes a digital servo DSP.

Functions and Features

• RF signal generation (with built-in gain adjustment

VGA circuit)

• RF peak detection and generation

• RF bottom detection and generation (with time constant

switching)

• Built-in RF equalizer amplifiers (two systems)

• FE amplifier (with built-in balance adjustment VCA and

offset cancellation pin)

• Three-beam TE amplifier (with built-in balance

adjustment VCA and offset cancellation pin)

• Reflection amplifier

• DPD circuit

• Tracking hold circuit

• Push-pull TE amplifier (with built-in balance adjustment

VCA)

• Built-in wobble detection bandpass filter

• APC circuits (two systems)

• Defect detection circuit
