CP2114 Crystal-less USB-to-I2S Audio Bridge-Image

Silicon Labs’ CP2114 device is the industry’s first crystal-less USB-to-I²S digital audio bridge designed to support a wide range of codecs and digital-to-analog converters (DACs) used in USB-based audio applications. The CP2114 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, navigation systems and VoIP systems.

The CP2114 device brings plug-and-play simplicity to audio design in a low-cost, highly-integrated single-chip solution.

  • USB crystal-less operation: eliminates need for external crystals and associated components; reduces BOM and design complexity
  • Multi-codec and audio DAC support: no external memory required; configure practically any external codec and perform in-field upgrades; USB audio class compatible (no need to install drivers)
  • Small 5 x 5 mm QFN-32 package: reduces PCB space by ~50% compared to competitive solutions; ideal for space-constrained portable audio applications
