plc has released a set of flexible and feature-rich SoC solutions CSR8645 and CSR8670, which has set a new standard for wireless audio quality. Consumer electronics OEMs can use these two chips more conveniently, quickly and economically to bring high differences to the market Home entertainment and portable audio products.
The two original members of the next-generation CSR8600 wireless consumer audio platform family embody CSR's unique audio processing technology, and also have wired audio capabilities, which can expand and improve the use of wireless audio products, even when their battery is exhausted or When wireless connection is forbidden, it can also be used on civil airliners. At present, these two platforms have been selected by many first-class customers and are developing products.
Both SoCs can use CSR audio processing and Bluetooth wireless connection technology to wirelessly transmit the highest stereo audio quality to home entertainment systems. Both SoCs can support TVs, other connectable home applications, and smartphones. Tablet PC, PC and many other consumer products. CSR's aptX ™ high-fidelity audio technology can provide excellent stereo sound for wireless speakers or headphones via Bluetooth connection, while CSR's Clear Voice Capture (CVC®) technology can provide acoustic echo and noise cancellation for high-quality speakers.
Paul Wilson, Product Marketing Manager, CSR Audio and Consumer Business, said: "CSR8645 and CSR8670 provide our customers with flexible audio system chip solutions that can be used to develop more highly differentiated products and get to market faster, In order to improve our own competitiveness. Through these two SoCs, we have set a new standard for wireless audio quality and provided a revolutionary consumer audio platform because it can not only support traditional audio applications, but also create new consumer applications and shape parameters. .
CSR8645 and CSR8670 were exhibited at the IFA2011 Global Trade Fair held in Berlin, Germany on September 2-7.
Wired alternative
CSR8645 and CSR8670 can help OEM manufacturers to develop enhanced battery-powered wireless audio products that can be used as wired devices, and can also be wired by directly inserting audio devices without Bluetooth connectivity. The wired audio feature also allows the device to continue to be used when the battery is low, or when the wireless connection is disabled or inconvenient to use. CSR8645 and CSR8670 audio products can obtain audio input through analog connection, such as standard 3.5 mm audio interface and USB connection. The latter's other advantage is that it can be charged while listening to music.
High-quality aptX Bluetooth audio designed for mainstream products
CSR8645 is the first CSR audio platform solution to implement aptX technology in ROM mode, marking CSR's commitment to apply aptX high-quality audio technology to the mass market. The CSR8645 is designed to provide superior sound effects, combined with a variety of core, market-leading features-such as multiple preset parameters, fully configurable, and adjustable EQ-concentrated in a flexible, highly adjustable, ROM-based solution. This solution is more suitable for mainstream consumer audio products that focus on cost, and these areas often pay more attention to time to market.
The best is getting better
CSR8670 is the most powerful, flexible and integrated wireless audio solution produced by CSR. Customers can use its advanced functions-such as support for up to 6 digital microphones and capacitive touch controller-to develop a variety of Innovative consumer audio equipment. With a lightweight packaging solution and reduced demand for external passive components,
CSR8670 can save up to 60% of printed circuit board space for manufacturers and achieve minimum production costs.
By integrating support for capacitive touch sensors, the CSR8670 helps design products that have a smoother touch interface and are more pleasing to the eye. The touchpad can be set to slide or swipe operation. The touchpad is overall controlled by software, which makes it easy to set up individual applications.
CSR8670 contains all the features of CSR8645. However, instead of using ROM-based solutions, CSR8670 uses embedded flash memory, which allows OEMs to use CSR software development kits, CSR eXtension partner solutions and custom software designs to develop their own custom software and products with unique features. Achieve maximum product differentiation.
Enhance development experience
The dual-core architecture of the CSR8670 includes an application processor, an ultra-low-power Kalimba DSP, and embedded flash memory, which enables the CSR8670 to provide a very flexible solution and achieve a highly differentiated product. The enhanced Kalimba DSP coprocessor can perform various signal processing functions at the same time when receiving data. The receiving mode can be any of the following: wireless, digital or analog audio streaming.
CSR's full set of CSR8600 product series setup tools, and the Audio Development Kit (ADK) for CSR8670-based product design can help manufacturers develop highly differentiated, feature-rich, and wireless or wired consumer audio applications, No need to spend a lot of energy on software and hardware development.
Through the eXtension partner program, CSR will provide a large number of third-party audio enhancement software plug-ins for the on-chip DSP of CSR8670, which will help consumer electronics manufacturers choose from a large number of solutions and enjoy the convenience they bring, thus Further shorten the product design cycle.
