NXP Semiconductor's largest car entertainment semiconductor supplier has launched SAF775x, which is fully integrated on a single chip. SAF775X is the third generation of NXP's popular automotive radio and audio DSP product line, and is the industry's first RFCMOS single-chip with multi-tuner such as embedded AM, FM and DAB. Improved audio processing capabilities, new products achieve excellent reception performance. At the same time, the SAF775X significantly reduces the system cost through the reduced peripheral material.
Characteristics
• Double-tunator RFCMOS integrated car radio solution
• Multi-standard (including DAB) front end
• DSP-based AM / FM radio processing
• Advanced multi-core audio subsystem
• Sliced microcontroller
• Extensive digital and analog interfaces and I / O
• Integrated Tensilica HiFi 2 audio digital signal processor, product customization
NXP has introduced the status diversity of the FM dual coordinator in a few years ago, using two tuner to obtain a better reception effect. However, so far, the two tuners are still their respective high-frequency receiving chips, but also external devices that are digital signal processing chip (DSP). To avoid interference and mating different process techniques for simulating RF tuner and DSP technology, the tuner is separately separate devices. The SAF775X launched, NXP re-established a new milestone of radio processing, integrating two independent tuners on a single grain (Die), creating a higher integration solution, significantly reduced system cost. This integrated dual tuner device is more than twice the processing capability of the previous generation products, achieving excellent wireless performance and better comprehensive reception quality.
In addition, SAF775x has open programmable. This product includes "open" Tensilica HiFi 2 audio DSP, customers can write programs to create product features, or run third-party software vendors. This makes car radio manufacturers do not need to adopt expensive external ICs It is also possible to selectively and elastically make a market-related in-vehicle information entertainment solution.
Wei Shitong is a leading in-vehicle information entertainment system supplier, which is closely working with NXP's development process to ensure early adoption of NXP tuner and DSP technology.
The global innovation and technical director of Weith Tong, explained: "Wei Shichong is committed to innovation technology, improving the inside entertainment experience. Excellent voice quality and radio receiving effect are the basic expectations of customers, and increase the" open "DSP core, make Wei Shirong can develop exciting, differentiated and customer-centered firmware. "
Another advantage that the new SAF775X brings to the market is its advanced audio processing power. Customers can use HIFI 2 audio DSP to perform third-party vendors, such as ARKAMYS, or AM3D. On the DSP of HiFi 2 audio, active engine noise cancellation is another innovative application: annoyance interference during music play and driving can be deleted by audio software. Combined with third-party software, SAF775X reduces unnecessary noise in a low cost manner to restore satisfactory raw sounds.
Torsten Lehmann, senior vice president and general manager of NXP Semiconductor Car Entertainment System, said: "SAF775X is a major breakthrough in the industry, two tuner works independently on the same chip, but also has multiple digital processor cores, currently No other semiconductor company can achieve this level of RFCMOS integration. This integration reduces the overall cost, and significantly reduces the space occupied by the application, and achieves good reception and sound performance. We are very happy that Wei Shitong has decided to use us. SAF775X chip, they are leading branded brands with a leading level in-level car information entertainment system.
