VS1053 – A multi- format high performance audio codec<br />Tampere, Finland, 13th of September 2007 - VLSI Solution announced today the<br />VS1053 audio decoder/encoder IC.<br />VS1053 is the most advanced slave audio circuit of VLSI Solution's product family. In<br />addition to being able to decode MP1, MP2, MP3, WMA, WAV, IMA ADPCM,<br />General Midi 1, Ogg Vorbis, LC- AAC and HE- AAC file formats, it can also record in<br />IMA ADPCM and Ogg Vorbis file formats.<br />The device features low power and high performance. The integrated DAC has 100<br />dB SNR, thus it can accurately reproduce all industry standard formats. The<br />sophisticated HE- AAC decoder is able to provide high quality sound for low bit rate<br />internet streaming files.<br />The on- chip stereo ADC features over 90 dB SNR, thus providing high- quality<br />recording from the line out or headphone connectors of external music devices. For<br />recording, Ogg Vorbis encoder can be loaded into the customization RAM of the<br />device to achive near CD quality stereo sound at medium bit rates (100 kbit/s), or<br />speech- quality mono sound at bitrates lower than 20 kbit/s. The Ogg Vorbis encoder<br />will be available for free download in October 2007.<br />The device has 16 KiB of customization program RAM memory which is more than<br />three times the memory of VLSI's earlier audio codecs. The program RAM broadens<br />the capabilities of VS1053 to include new audio applications such as echo<br />cancellation for mobile phone or VOIP.<br />VS1053 contains VLSI Solution's proprietary EarSpeaker Spatial Processing<br />technology. This emulates a listening room to move music outside the listener's head<br />as if it would come from real loudspeakers.<br />The device runs with any external clock<br />between 12 and 13 MHz. This makes it<br />possible to use the USB or GSM clock<br />domains of an existing application.<br />VS1053 is offered in LQFP- 48<br />7x7x1.4mm RoHS compatible package.<br />Engineering samples and evaluation kit<br />are immediately available. Volume<br />production is expected to start<br />Q1/2008.<br /><br />www.vlsi.fi<br />索取样片：www.megadiy.com<br /><br /> 相关链接:<a href='http://www.megadiy.com'>http://www.megadiy.com</a> |
