Silicon Laboratories has introduced a 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 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 synchronisation, which poses complex development challenges. To address these needs, the CP2114 provides a highly integrated, plug-and-play solution for streaming audio between USB and I²S.
The IC integrates a USB 2.0 full-speed function controller, a USB transceiver, crystal-less oscillator, one-time programmable ROM, UART, IIC and I²S interface. It requires no external memory when combined with a codec or DAC, further minimising system BOM cost.
The device 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.
The CP2114 uses the standard USB audio device class that is natively supported by most operating systems, eliminating the need to develop and install custom USB software drivers. Host programming capabilities also enable developers to configure practically any external codec or DAC and perform in-field upgrades.
