Silicon Labs (core department laboratory limited company) Claim to introduce Si4830 AM/FM receiver chip at IIC-China spring of this year exhibition, thus has brought the mechanical type and tuned the simulation radio digital characteristic and integrated advantage. Si4830 AM/FM receiver chip introduced newly in core subject laboratory has reduced the time and system cost of product design, have raised the manufacture efficiency of the polytype radio products, such as the porable radio set, stereophonic receiver, clock and desk lamp type radio, toy radio, desk-top radio, MP3 music, radio systems mini, behind load by radio, earphone radio and gift radio of year.

Si4830 is the industry the first adopts CMOS technical wheel to adjust AM/FM radio chip, it in single to integrate, input from the aerial into the intact AM/FM radio function that the audio frequency outputs while being on-chip, have dispelled all assemblies needing to tune by hand. The high integration density makes its quantity of required components and parts reduce by more than 80% than the existing solution. Use Si4830 not to need external microcontroller, AM/FM electric-wave filter, tuning inductance and other components, need, reprocess and adjust by hand, apparent to lower the material bill and staff cost, the developer only needs to add aerial, machinery tuning and volume control gyro wheel, amplifier and two AAA batteries, Si4830 receiver chip has already designed the platform as a low-cost radio.

Silicon Labs broadcasts the manager Natalian Zhai of product market and says: "China is the world manufacturing center of AM/FM radio, the annual output exceeds 200 million, and over 60% of the AM/FM radios use the mechanical type to tune, Si4830 has offered the ideal solution for this market. "

Si4830 AM/FM the intersection of receiver and chip direct global the intersection of radio and manufacturer but design, especially the manufacturers in China against, at present, China is still the world manufacturing center to adopt technical design AM/FM radio of traditional simulation, supply over 100 million radios of simulation to the whole world every year. The technology-intensive radio of simulation is designed to usually need dozens of discrete components, need a large amount of reprocessing in the course of making and assembling and adjust by hand. Si4830 needs only 12 elements pasted on surface, only needs the area of lateral circuit board of 20mm2. Such exquisite design and convenient face have disposed and further lowered costs, make AM/FM function expand to the multi-terminal products.

"It does not have other alternative schemes that a lot of mechanical types tune AM/FM radio manufacturers, have to adopt the labor-intensive, separates the way and constructs and makes the low-cost radio, "Silicon Labs broadcasts the executive vice president Dave Bresemann of the products to represent, "our composite signal receiver chip Si4830 applies advanced digital broadcasting technology to simulation, mechanical type and tunes the market of radio, through lowering production cost, increase AM/FM radio function to many kinds of consumption electronic products, create the new business opportunity for the customer. "

Si4830 has fairly good degree of sensitivity, selectivity, signal to noise ratio and soft squelch muting, can realize the automatic, rigorous tuning of the wave band of global AM and FM, thus can strengthen users' radio to tune and experience with the audio frequency greatly. Si4830 adopts SSOP easy to process to capsulate, it is a radio platform easy to design and make, because the single design is a satisfiable global market standard, including the frequency band 64MHz in the Chinese campus is to ETSI radiation and interference-free standard.

Si4830 AM/FM receiver chip has already been supplied now, at the time of 10,000 drops of amount of purchase, 2.10 dollars get up at unit price, adopt 24 base pins SSOP to capsulate. Si4830-DEMO designed to accelerate the products and assess and develop demonstrates the kit has already been supplied now, propose the price of 50 dollars.
