Overview
The LA9703W 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
• Generation of RF signal (with built-in RFAGC circuit).
• Generation of RF - peak detection.
• Generation of RF - bottom detection (time constant changeover).
• RF equalizer incorporated (fO, boost variable).
• FE Amplifier (Balance Adjustment VCA Built in).
• 3-beam Tracking Error Amplifier (Balance Adjustment VCA Built in).
• Reflect Amplifier.
• DPD Circuit.
• Push-pull TE amplifier.
• Wobble detection BPF built in.
• APC Circuit (two channels).
