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
