MN662710RA Datasheet | Panasonic

For Audio Equipment Signal Processing LSI for CD Players Overview The MN662710RA is a CD signal processing LSI that, on a single chip, bines an optics servo for the CD player (focus, tracking, and traverse servos), digital signal processing (EFM demodulation and error correction), digital servo processing for the spindle motor, digital filter, and D/A converter, so thus covers all signal processing functions from the head's RF amplifier onward. The MN662710RA is also usable as a CD signal processing LSI for double-speed CD-ROM playback. Do not, however, use the audio equipment D/A converter during double-speed playback. Digital audio interface (EIAJ format) Audio data serial interface (Spindle motor servo) CLV digital servo (Audio circuits) Operation guaranteed only for normal playback speed Digital filter using 8-fold oversampling Built-in D/A converter (1-bit D/A converter) Built-in differential operational amplifier (±PWM output) (Other) Built-in playback pitch control function (normal speed only) (±13%) Operating voltage 4.5 to 5.5V Features (Optics servo) Focus, tracking, and traverse servos Automatic adjustment functions for FO/TR gain, FO/ TR offset, and FO/TR balance Built-in D/A converter for drive voltage output Built-in dropout countermeasures Anti-shock functions Built-in track cross counter Support for both linear motor and screw-based traverse mechanisms Support for 3- and 1-beam systems (Digital signal processing) Playback switchable between double-speed and normal speed Built-in DSL and PLL Frame synchronization detection, holding, and insertion Subcode data processing Q data CRC check Built-in Q data register CIRC error detection and correction C1 decoder: duplex error correction C2 decoder: triplex error correction Built-in 16-K bits of RAM for de-interleaving Audio data interpolation Average, hold of previous values Soft muting Digital attenuation (256 levels) Software attenuation (256 levels) Audio data peak level detection...
