MN662747RPH Datasheet | Panasonic

For Audio Equipment Signal Processing LSI for CD Players Overview The MN662747RPH is a CD signal processing LSI that, on a single chip, bines optics servos 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. (Audio circuits) Digital filter using 8-fold oversampling Built-in D/A converter (1-bit D/A converter) Built-in differential operational amplifier (secondary low pass filter) (Other) Built-in playback pitch control function (normal speed only) (± 13%) Support for quadruple-speed playback (digital servo and signal processing block only) Built-in support for jitter-free disc rotation synchronization playback Oscillator shutdown mode Power management mode Operating voltage 4.5 to 5.5 V 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 Traverse speed detection function (Digital Signal Processing) Built-in DSL and PLL Frame synchronization detection, holding, and insertion Subcode data processing Subcode Q data CRC check Built-in subcode 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 use in deinterleaving Audio data interpolation Averaging or retention of previous values Digital attenuation (- 12 d B) Audio data peak level detection function Digital audio interface (EIAJ format) Audio data serial interface for input and output (Spindle Motor Servo) CLV digital servo Switchable servo gain Applications CD players Pin Assignment For Audio Equipment 60 59 58 57 56 55 54 53 52 51...
