Silicon Labs announces the launch of Si4830 AM / FM receiver chip
Silicon Laboratories, a leading manufacturer of high-performance analog and mixed-signal ICs, announced the launch of the Si4830 AM / FM receiver chip, thereby bringing the benefits of digital performance and integration to mechanically tuned analog radios. Silicon Labs' new Si4830 AM / FM receiver chip reduces product design time and system cost, and improves the manufacturing efficiency of many types of radio products, such as portable radios, stereo radios, clock and desk lamp radios, toy radios and gift radios .
The Si4830 is the industry's first AM / FM radio chip with CMOS technology and provides complete AM / FM radio functions in a single chip, including from antenna input to audio output. The high level of integration makes it require more than 80% fewer components than existing solutions. Using Si4830 eliminates the need for external microcontrollers, AM / FM filters, tuning inductors and other components, significantly reducing bill of materials and labor costs. Developers only need to add antennas, mechanical tuning and volume control rollers, amplifiers and two AAA batteries. Yes, the Si4830 receiver chip has become a low-cost radio design platform.
The Si4830 AM / FM receiver chip is designed for global radio manufacturers, especially manufacturers in China. At present, China is still a world manufacturing center that uses traditional analog technology to design AM / FM radios. 100 million units. These analog technology-intensive radio designs usually require dozens of discrete components and require extensive reprocessing and manual adjustment during manufacturing and assembly. The Si4830 requires only 12 surface-mount components and only requires 20mm2 of single-sided circuit board area. This exquisite design and convenient board configuration further reduce the cost and extend the AM / FM function to more end products.
"Many mechanically tuned AM / FM radio manufacturers have no alternatives and have to construct and manufacture low-cost radios in a labor-intensive, discrete manner," said Dave Bresemann, vice president of broadcast products at Silicon Labs, "our mixed signal receiver The chip Si4830 applies advanced digital broadcasting technology to the analog and mechanically tuned radio market, and creates new business opportunities for customers by reducing production costs and adding AM / FM broadcasting functions to a variety of consumer electronics products. "
The Si4830 complies with the European EN55020 standard and provides easy, accurate, and reliable tuning for the global FM band 64-108MHz and AM band 520-1710kHz.
Price and Availability The Si4830 AM / FM receiver chip is available now. With a purchase price of 10,000 pieces, the unit price starts at $ 2.10 and comes in a 24-pin SSOP package. The Si4830-DEMO demonstration kit designed to speed up product evaluation and development is now available, and the recommended price is $ 50.
