Silicon Laboratories Inc. introduced the industry’s first crystal-less USB-to-I²S audio bridge designed to support a wide range of codecs and digital-to-analog converters (DACs) used in USB-based audio applications. The new CP2114 audio bridge chip simplifies the process of transferring audio data from USB to I²S without time-consuming code development, speeding time to market for USB audio accessories such as speakers, headphones, music boxes, point-of-sale terminals, navigation systems and VoIP systems. USB system development often involves significant expertise, design effort and cost to overcome implementation issues ranging from compatibility to poor performance. USB-to-I²S audio data transfer also requires sophisticated clock synchronization, which poses complex development challenges. To address these needs, Silicon Labs’ CP2114 audio bridge provides a highly-integrated, plug-and-play solution for streaming audio between USB and I²S.
The CP2114 audio bridge integrates a USB 2.0 full-speed function controller, a USB transceiver, crystal-less oscillator, one-time programmable ROM, UART, IIC and I²S interface into a single-chip solution.
