ST-Ericsson develops new chip that doubles music playback time on phones
ST-Ericsson, the recently-established joint venture between STMicroelectronics and Ericsson, announced the upcoming availability of the next-generation STw5211 mobile audio chip.
Reportedly, this new audio digital-to-analog converter (DAC) will enable manufacturers to build music-oriented handsets and MP3 players capable of delivering the highest levels of audio quality, as well as longer playback time – basically, double the typical 10-hour playback time.
This can be achieved thanks to ST-Ericsson’s combination of PTE (Playback Time Extender) processing technology with “102dB signal-to-noise ratio through the whole audio path”.
STw5211’s features include:
- 66dB THD (Total harmonic distortion)
- 8 to 192kHz sample rate conversion
- 32kHz RTC clock-only operationSystem clock generator
- 2.6 x 2.6mm footprint (only few external components required)
ST-Ericsson says that samples of STw5211 will be available in April, while volume production is scheduled for August this year.
