21ic News Silicon Labs has announced the industry's first single-die, fully integrated digital radio receiver solution from antenna input to audio output for portable and consumer electronics worldwide Developed by the market. Utilizing software-defined radio technology, the new Si468x receiver single-chip IC provides FM, HD RadioTM and DAB/DAB+ broadcast capabilities for a wide range of audio applications, from price-sensitive clocks and desktop radios to mainstream mini/micro audio systems And portable audio, as well as high-end multimedia devices with display capabilities, such as mobile phones, tablets and personal navigation devices. This article refers to the address: http:// Digital radio technology is a new generation of radio broadcasting technology. In addition to providing better audio quality than traditional AM/FM radios, it also transmits program information, weather forecasts, news headlines, music artist and track names, traffic information and other data. One of the reasons for the slow adoption of digital radio is the high cost of high-performance, low-power RF solutions currently available to the consumer electronics market. The Silicon Labs Si468x family fully meets the needs of the consumer electronics radio market by providing advanced single-die solutions that reduce system complexity, bill of materials (BOM) devices, and power consumption while maintaining RF performance. Utilizing Silicon Labs' patented low-IF digital receiver architecture, the Si468x family offers better RF performance than existing consumer-grade digital receiver solutions. The Si468x receiver supports auto-calibrated digital tuning and FM search based on multiple signal quality and bandwidth parameters, providing flexible audio processing features including noise cancellation, configurable FM soft mute, FM de-emphasis and FM hi -cut filter. The Si468x family integrates most of the external components required for digital radio receiver systems, including RF tuners, baseband and stereo audio DACs, enabling developers to reduce system cost, size and complexity. The wafer-level chip scale package (WLCSP) of this family supports a very compact design that enables a complete digital radio receiver with only 12 external components in less than 100 square millimeters. The Si468x receiver is available in a small package. By integrating RF tuner and baseband functions on a single die, the Si468x family eliminates radio self-interference and simplifies system design, verification and testing. Highly integrated features simplify board layout, reduce board space requirements, and increase system stability, making the receiver ideal for single board and miniaturized designs because of its high performance, size, and reliability requirements. . The Si468x receiver is also power and space sensitive portable by offering the smallest package and lowest power consumption on the market (less than 60 mW in analog FM mode, less than 95 mW in HD Radio and DAB/DAB+ mode). Ideal for applications. James Stansberry, vice president and general manager of broadcast products at Silicon Labs, said: "Digital radio is the next wave of the broadcast audio industry, providing CD-quality sound for radio listeners and a host with innovative broadcast data services. By developing 'on-chip numbers With the radio' solution, we are well positioned to meet the needs of the global digital radio market, enabling developers to reduce costs and simplify their portable and home audio product designs while providing consumers with the highest RF performance and sound quality." The Si468x receiver supports worldwide analog FM radio reception and has a complete decoder supporting the European Radio Data System (RDS) and North American Radio Broadcast Data System (RBDS) standards, including required symbol decoding, block synchronization, error detection and correction Wrong function. The Si468x family is the first digital radio receiver single-chip IC that is truly iBiquity-certified and provides HD Radio standard support for portable and consumer electronics applications. The Si468x receiver family is compatible with the European Eureka 147 DAB and DAB+ standards and is fully compliant with the UK's minimum requirements for DAB and DAB+ personal and home digital radio receivers. Price and availability The Si468x digital radio receiver is available now in volume and is available in a 7 mm x 7 mm 48-pin QFN package and a 3.2 mm x 3.8 mm WLCSP package, making it ideal for portable and space-constrained applications. At 10,000 units, the Si468x receiver series starts at $5.62. To simplify the design of digital radio systems based on the Si468x family, Silicon Labs also offers a complete evaluation kit for $550.
