? NPCA110M audio enhanc ing engine and codec ? 2011 nuvoton technology corporation www.nuvoton.com product brief november 2011 revision 1.0 NPCA110M audio enhancing engine and codec general description the nuvoton NPCA110M device is a member of nuvoton?s sound enhancing family optimized for mobile applications such as tablets, mobile phones and netbooks. it provides codec functionality to support stereo microphone inputs and either dual-stereo dacs or digital outputs, for built-in speakers or a headphone jack. the NPCA110M integrates waves ? maxxaudio 3 sound enhancement algorithms. these are proprietary, patented, psychoacoustic algorithms that compensate for the acoustic limitations of small ce devices. the maxxaudio 3 algorithms enable reproduction of rich content, with a wide dynamic range and a full frequency range, on a limited audio system. for low-frequency reproduction, maxxbass ? uses a patented psychoacoustic technique to create a perceived low bass, which can be extended up to 1.5 octaves lower than the original. this technique reproduces full and rich sounding bass tones. power handling is done by maxxvolume ? , which utilizes the power amplifiers and speakers to their full extent yet avoids clipping and distortions. the maxxaudio 3 software suit e provides additional algo- rithms that enhance the over all sound quality, such as maxx3d, which widens the stereo image, and maxxtreble, for reproducing crystal clear high frequencies. to design a resonance-free audio system, ma xxeq provides a flexible equalizer with 10 bands. the maxx family of devices includes: high-performance, 24-bit audio enhancing device pre- programmed with waves maxxaudio 3 algorithms optional audio adc with stereo microphone support optional audio dac digital i/o and other features for high-performance audio systems outstanding features improves audio quality for low-performance speakers system-level bom savings stereo operation i2c controlled 24-bit accuracy audio algorithms ? ? ? ? ? ? ? audio input ? up to two i2s or synchronous serial interface (ssi) inputs ? up to three stereo analog inputs with microphone support: typical snr of 90 db; typical thd of ? 75 db audio output ? optional generation of bass channel for sub-woofer ? up to three i2s or ssi outputs ? up to four analog outputs: typical snr of 96 db; typical thd of ? 86 db several general-purpose digital signals available to the application (gpios) typical operational power target down to 0.05w power-down target of less than 0.3 mw 3.3v (i/o, analog) and 1.8v (core) operation mobile device system block diagram NPCA110M i2s analog headphones gpios amp power amplifiers speakers optional r l bass i2c chipset i2s microphones maxxbass ? maxxtreble maxxeq maxxvolume ? maxxleveler maxxdialog www.datasheet.co.kr datasheet pdf - http://www..net/
www.nuvoton.com 2 revision 1.0 NPCA110M features bus interfaces synchronous serial interface (ssi) ? compatible with i2s ? master and slave timing support i2c interface ? compliant with i2c-bus specification revision 1.0, 1992 ? master or slave interface ? supports 7-bit address mode audio enhancing engine processing unit ? 24-bit accuracy ? 125 mips audio algorithms sample frequency of 44.1 khz or 48 khz maxxbass ? ? patented waves maxxbass psycho-acoustic bass extension delivers a more natural sound than tradi- tional bass boost technologies, which use eq and can overpower your system. maxxbass analyzes low frequencies to create harmonics that are per- ceived as lower, deeper tones. maxx3d ? maxx3d extends the span of stereo-side content while maintaining the integrity of unprocessed cen- ter content. ? maxx3d for speakers improves the stereo separa- tion of speakers, widening the stereo field for optimal imaging. ? maxx3d for headphones improves stereo percep- tion, restoring the original listening balance to pro- vide more natural sound. maxxtreble ? maxxtreble delivers crystal clear high-frequency en- hancement for increased rms without exceeding the system ceiling. its prop rietary algorithm restores luster to over-compressed formats to provide the perfect listening experience. maxxeq ? maxxeq provides the ability to design eq curves and shape sound with surgical precision, using up to 10 programmable filters with bell, shelf, low pass, and high pass, plus adjustable frequency, gain, and q parameters. maxxeq?s intuitive graphic user in- terface makes click-and-drag filter design fast and easy. maxxvolume ? ? maxxvolume is an all-in-one volume control, with high-level compression to increase rms levels, low-level compression to increase the clarity of soft sounds, noise gating to eliminate signal and system noise, and leveli ng to smooth out volume levels. maxxleveler ? maxxleveler regulates the perceived volume of the audio, keeping all audio content at the same level. maxxdialog ? maxxdialog is a revolutionary new technology that enables users to adjust center channel dialog levels without affecting the rest of the audio mix. based on the waves center pro audio plug-in, maxxdialog de- livers clear, crisp dialog that does not disappear be- hind loud music and sound effects. sub-woofer ? enables separating low-frequency content and di- recting it into a third audio channel, for driving a sub- woofer. straps, clocks, supply and package information strap input controlled operating modes ? pll reference clock select (ref strap) ? test mode select (ntest strap) ? i2c master or slave select (i2cms strap) ? boot options ? rom code operation ? loadable algorithms for new functions or rom code patching input clocks ? ssi / i2s clock: 64x of sample frequency ? optional crystal oscillator or input clock power supply ? 3.3v (i/o, analog) and 1.8v (core) operation power-save modes ? clock switch to a lower frequency ? wait instruction (clock stopped) ? pll power-down package ? 6 x 6 mm, 40-pin quad flat no-lead (qfn) package maxx bass maxx 3d maxx treble maxx eq leveler maxx volume maxx dialog algorithm processing chain www.datasheet.co.kr datasheet pdf - http://www..net/
