Silicon Labs offers crystal-less USB-I2S bridge




Silicon Labs’ CP2114 device is the industry’s first crystal-less USB-to-I²S audio bridge, designed to support a wide range of codecs and DACs in USB-based audio applications. The CP2114 simplifies the process of transferring audio data from USB to I²S without any code development, speeding time to market for USB audio accessories such as USB speakers, USB headphones, and USB music boxes, as well as VoIP systems. Available in a small-footprint, cost-effective 5 mm x 5 mm package, the CP2114 is ideal for space-constrained portable audio applications.

Features

  • USB crystal-less operation: eliminates the need for external crystal and associated components, reducing BOM cost and design complexity
  • Supports a wide range of codecs and audio DACs
  • Small-footprint package

Applications

  • USB speakers/headphones/headsets
  • Point-of-sale terminals
  • Navigation systems
  • Music boxes
  • VoIP phones

Silicon Labs offers crystal-less USB-I2S bridge




Silicon Laboratories has introduced a crystal-less USB-to-I2S audio bridge designed to support a range of codecs and digital-to-analogue converters (DACs) used in USB-based audio applications.

USB-to-I²S audio data transfer also requires sophisticated clock synchronization, which poses complex development challenges.

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.

The device also requires no external memory when combined with a codec or DAC.

The CP2114 audio bridge supports multiple mainstream DACs and codecs from Wolfson Microelectronics, Cirrus Logic and Texas Instruments, giving customers the flexibility to implement their own preferred audio chipset solution.

Silicon Labs offers evaluation kits pre-populated with these popular DAC and codec platforms to further speed design time.
