LA9703W

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).
