ST-Ericsson, the recent joint venture between STMicroelectronics and Ericsson, has announced its next-generation STw5211 mobile audio chip.The new Stw5211 includes the innovative Playback Time Extender (PTE) processing technology developed by the company, as well as 102dB signal-to-noise ratio across the entire audio path. OEMs are offered the possibility to develop music-oriented mobile phones that would be able to provide users with the "highest levels of audio quality."
STw5211 combines ST-Ericsson's innovative Playback Time Extender (PTE) processing technology with 102dB signal-to-noise ratio through the whole audio path, allowing OEMs to build music phones with the highest levels of audio quality and double today's typical 10-hour playback time. Available as a single-chip solution in an ultra-small, wafer-level chip scale package (WLCSP), STw5211 is the market's most integrated and cost-effective audio solution to boost playback time.
The new mobile audio chip is also able to provide extended playback time, doubling today's existing typical 10-hour period. The Stw5211 is available as a single-chip solution that sports an ultra-small, wafer-level chip scale package, proving to be the most integrated and cost-effective audio solution on the market.
"STw5211 was developed to address increasing demand for mobile music handsets with both higher audio quality and longer playback time," said Monica de Virgiliis, Vice President, Wireless Multimedia Group, ST-Ericsson. "Typically, power consumption increases as features are enhanced and quality improved; however, STw5211 with PTE technology allows music to be played autonomously while the rest of the platform is switched into a power-saving state. This results in a substantial increase in battery life without any compromise in audio quality for the consumer."
