Datasheet

A Hi-Res Player Evaluation Board will be unveiled by VLSI Solution at electronica on 8^th to 11^th November. The VS1005 Hi-Res Player Evaluation Board is based on VLSI Solution's VS1005 SoC, a highly integrated all-in-one IC for audio processing applications, and VLSI Solution's high-resolution audio decoder libraries.

It is intended as a basis for both performance evaluation and development of customers' own high-resolution audio products.

Highlights of supported high-resolution, lossless audio decoders include Apple lossless ALAC (up to 24-bit 96kHz), FLAC (up to 24-bit 96 kHz), AIFF (up to 32-bit 352kHz), RIFF WAV (up to 32-bit 352kHz, including DXD), and DSD (up to 1-bit 11.3MHz DSD256, with on-chip volume control). In addition to these formats, popular compressed audio formats like MP3, Ogg Vorbis, WMA, and AAC are supported.

After decoding, audio can be forwarded either digitally to an external decoder, or to the integrated DAC of VS1005.

VS1005's digital-to-analogue converter data path contains a fully-digital, PLL-free and jitter-free 24-bit sample rate converter which resamples audio right up to 6.144MHz. At this high frequency the audio signal is converted to the analog domain, and output through VS1005's integrated analog stereo earphone amplifier.

All audio, including DSD, can be sent to both optical S/PDIF and an I2S bus for external decoding, after being converted by VS1005's high-quality, jitter-free 24-bit resampling hardware to 96kHz for highest possible audio fidelity and compatibility with ampliefiers.

The VS1005 Hi-Res Player's playback time is up to 120 hours with a 3.7V 2,500mAh battery.

We welcome our customers to listen to the VS1005 Hi-Res Player and meet our technical personnel at our booth at electronica, 8^th to 11^th November, München Messehalle, Germany, hall A4, booth 481.
