STEREO SOUND CODEC
The µPD63310 is an LSI that features two channels each of on-chip 16-bit ADC and DAC circuits for mutual conversion between digital signals and audio signals (having a maximum signal bandwidth of 24 kHz).
The analog signal input block enables mixed input of four different stereo signals and one monaural signal, and the volume of each signal can be controlled before mixing. The µPD63310 also features two on-chip microphone amplifiers (mic amps) and gain is adjustable between 10 and 30 dB.
The analog signal output block enables mixed output of analog signals output by the DAC and four different stereo analog signals, and the volume of each signal can be controlled before mixing.
The digital audio signal I/O block supports a serial interface for audio applications (two’s complement, MSB first).
A 6-bit parallel port are used for the various volume settings, with volume settings selectable (in 1.5-dB steps) from – 46.5 dB to 0 dB, as well as a mute setting.
FEATURES
• Two channels each of ∆Σ type ADC and DAC
• On-chip mixing circuit in analog I/O block
• Low-noise mic amps for two channels on chip
• On-chip reference voltage power supply (1.4 V TYP.)
• ADC and DAC digital filter characteristics
Pass band ripple : ±0.1 dB (0 to 0.454 fs) for ADC and DAC
Stop band attenuation : 75 dB (0.546 fs or above) for ADC and DAC
• Sampling frequency (fs): 2 to 48 kHz (256-fs master clock is input from an external source)
• Low voltage operation: +3 to +5.5 V single power supply
• Wide operating ambient temperature: –20 to +80°C
• Low power consumption: 120 mW (when using 3-V power supply), 250 mW (when using 5-V power supply)
• 80-pin plastic TQFP
RECOMMENDED USES
• Speech recognition system, including car navigation system
• PC sound system
