The radio ICs provide an “all-in-one” single-chip receiver solution for tabletop and portable radios, stereos, mini/micro systems, boomboxes, clock radios, iPod docking stations, toy radios and many other consumer products containing wheel-tuned radios.
The wheel-tuned or 'analog-tuned' multiband radio product market exceeds 115 million units per year, according to Silicon Labs estimates. More than 90% of all ATxD radios including products for the global export market are manufactured in China.
Si4825/27/36 receivers offer the same exceptional RF performance, unmatched integration in CMOS, bill of materials (BOM) and labour cost reduction, and ease of design and manufacturing as previous generations of Si48xx radio ICs. In addition, the new receivers use a single band to cover a wider frequency range for FM and SW bands, and they also support TV audio carrier reception in the China market. The devices provide advanced audio conditioning for all signal environments, removing pops, clicks and loud static in challenging signal conditions.
The Si4825 mono-output, consumer-grade product and the Si4836 stereo-output, commercial-grade product are designed for the ATAD radio market. The Si4827 mono-output, consumer-grade product targets the ATDD radio market. Each receiver supports worldwide broadcast frequencies from 64-109 MHz in FM, 504-1750 kHz in AM and 2.3-28.5 MHz in shortwave (SW), enabling a single radio design based on the receivers to support all worldwide markets.
The Si4825/27/36 multiband receivers are available in a compact 16-pin SOIC package, enabling cost-efficient, single-sided PCB designs and easy handling in manufacturing lines. Samples and production quantities of the new receivers are available now. The Si4825 is priced at $1.56, the Si4827 at $1.76, and the Si4836 at $1.66 (10,000). To ease radio system design, Silicon Labs offers demonstration boards for each receiver product priced at $50.00.
