STw5094 is a low power Stereo Audio DAC device with Headphones Amplifiers for high quality MP3 and FM radio listening. The STw5094 includes also an high performance low power combined PCM CODEC ¤ FILTER tailored to implement the audio front-end functions required by low voltage low power consumption digital cellular terminals with added MP3 and FM radio listening.
STw5094 offers a number of programmable functions accessed through an I2C-bus compatible interface.
The STw5094 Stereo Audio DAC section is suited for MP3, or any other audio stereo source, listening. It supports all the MP3 rates from 8kHz to 48kHz. The audio data serial interface is I2S compatible and can be programmed to handle 16 to 24 bit word length input data. The internal D to A converters work with 18 bit input resolution.
The Stereo Headphones drivers can also be used for FM Radio listening via an auxiliary stereo analog input.A Loudspeaker driver can also be used for monophonic group listening.
The STw5094 Voice Codec section can be configured either as a 14-bit linear or as an 8-bit companded PCM coder. The Frame Synchronism frequency of the Voice Codec can be either the standard 8kHz value or the extended 16kHz one.
In addition to the Stereo Audio DAC and CODEC ¤ FILTER functions, STw5094 includes Tone ¤ Ring ¤ DTMF generator that can be used both in Audio Listening mode and in Voice Codec mode, a sidetone generation, a buzzer driver output and a remote control function tailored to handle an external on-hook off-hook button.
STw5094 Voice Codec fulfills and exceeds D3 ¤ D4 and CCITT recommendations and ETSI requirements for digital handset terminals. The Stereo Audio DAC
part fulfills and exceeds the requirements for MP3 quality and FM radio quality listening. Main applications include digital mobile phones, as cellular and cordless phones, with added low-power high-quality MP3 and ¤ or FM radio listening features, or any battery powered equipment that requires Stereo Audio DAC with Headphones drivers operating at low single supply voltage.
