Silicon Labs’ CP2615 digital audio bridge provides a plug-and-play USB to I2S connectivity solution. That eliminates the need for USB audio knowledge or protocol expertise. So enabling developers to focus on their end applications rather than firmware development.
Silicon Labs (also known as “core technology” has introduced a fixed function of the audio bridge device. There is USB and I2S serial bus interface between the transmission of digital audio data that provides a simple and complete solution. The new CP2615 digital audio bridge simplifies USB-to-I2S connectivity. So this is a cost-effective, space-constrained USB audio application that effectively reduces time-to-market for Android, Windows, Linux, and Mac operating systems. Particular target devices are Headset, speakers, MP3 accessories, navigation systems and sales terminals (POS) and so on.
Silicon CP2615 New Bridge for New Technologies
Here the USB connectivity is simple for consumers, USB audio design is challenging. And developers need a quick and easy way to add a USB connection to their audio accessories. So Silicon Labs’ CP2615 digital audio bridge provides a plug-and-play USB to I2S connectivity solution that eliminates the need for USB audio knowledge or protocol expertise. Thus enabling developers to focus on their end applications rather than firmware development.
The single-chip CP2615 audio bridge is available in a compact 5mm x 5mm QFN-32 package. And it is ideal for space-constrained printed circuit boards (PCBs) for portable audio applications. The fully functional CP2615 device integrates USB 2.0 full speed controller, USB transceiver, on-chip oscillator, I2S audio interface, I2C control interface and embedded flash memory for storage device configuration. This high level of integration requires no off-chip components. So significantly reducing PCB size and BOM costs.
CP2615 Available options and target applications
The CP2615 audio bridge provides a low-cost solution for mid- and low-end headphones that require 48kHz sampling rates. The small size device is also ideal for USB accessories and suitable for those who use analog jacks of high-end headset consumers. Many new smartphone designs are eliminating analog headphone jacks, providing only one USB connector to support charging and audio connections. Therefore, consumers need to buy simple, low-cost accessories. So that the 3.5mm analog jack connected to the USB-C to Micro USB adapter. So that they can continue to use its existing headphones.
Silicon Labs’ popular Simplicity Studio development environment includes a GUI-based Xpress Configurator tool that simplifies USB audio design. When using the Xpress Configurator tool, developers can configure and customize their digital audio applications in three simple steps. First is to connect the CP2615 bridge device. Then configure USB and audio parameters, and program the device. This configuration tool also allows developers to take advantage of Silicon Labs’ flexible factory programming options to accelerate time-to-market.
“Silicon Labs understands all the details of USB development, and we have passed years of USB expertise through plug-and-play USB connectivity solutions such as the new CP2615 audio bridge chip,” said Tom Pannell, senior director of marketing for Silicon Labs’ Internet of Things products. If you are developing USB-based digital audio applications, it will save time, effort and cost by using Silicon Labs’ CP2615 devices, Xpress Configurator tools and evaluation kits. ”
Silicon Labs is a leading provider of USB connectivity solutions. And offers a broad range of flexible USB product families, including fixed-function devices and general-purpose 8-bit and 32-bit MCUs with on-chip USB controllers.
