microcircuits radio si473x

The microcircuits of radio- and television tuners are not rarity, but for the specialists of company silicon laboratories, which works in the sphere of design and production of microcircuits for the mixed processing signals , seems to reach the new frontier in this region. Company officially presented the family AM/ Fm- receivers si473x. With their aid to realize the functionality of method AM/Fm- radiobroadcasting in the portable electronic devices became simpler than sometimes earlier.

The fact is that, in contrast to earlier accessible solutions, Si473x is integral AM/Fm- radio receiver, in which all blocks are concluded in one microcircuit. Earlier, the addition AM/Fm- radio required a sufficiently large quantity of components and much place on the printed-circuit board. As consequence, inexpensive and compact devices were limited to Fm- receiver. The single-hull tuner si473x requires altogether only two external component. Together with the microcircuit they occupy area 0,15 sq. see for the comparison â€“ according to the data silicon laboratories, the traditional realization necessarily more than 50 components, and the occupied by them area is equal to 10 sq. .

Simplicity of integration with the digital units and absence to the need for manual tuning with the production is the prime advantage of this product. Furthermore, Si4731 is only AM/Fm- receiver with support to the European system radio data system (RDS) and American radio broadcast data system (RBDS). Field of application of a new tuner are portable radio receivers, CPC, players MP3, universal portable players, electronic clocks, Home stereos-system, dock- station and cell phones.

The microcircuits si4730 and Si4731 are released in case of type QFN by the size of 3x3 mm with 20 contacts. Wholesale price Of si4730 is 4,87 dollars si4731 (with the support RDS/RBDS) is 5,53 dollars.
