Silicon Labs Introduces Highly Integrated Multi-Band Receiver Solution
This article refers to the address: http://
According to Silicon Labs, the market for rotational or "analog tuning" multi-band radio products exceeds 115 million units per year. More than 90% of ATxD radios are manufactured in China, including products for the global export market. As a pioneer in RF-in-CMOS multi-band receiver products in the rotating radio market, Silicon Labs has introduced third-generation single-chip receiver solutions that reduce the cost and complexity of radio products and simplify manufacturing for many consumers around the world. .
Like Silicon Labs' previous generation of Si48xx radio ICs, the new Si4825/27/36 receiver delivers superior RF performance, unmatched CMOS integration, lower bill of materials (BOM) and labor costs, and is easier to design and manufacture; In addition, the new receiver uses a single band to cover a wider range of FM and SW frequency bands and supports TV audio carrier reception in the Chinese market. At the same time, the radio chip provides advanced audio conditioning management for various signal environments, eliminating the noisy signal environment. The noise under.
The Si4825 mono output, consumer grade and Si4836 stereo output, commercial grade products are designed for the ATAD radio market; the Si4827 mono output, consumer grade products are targeted at the ATDD radio market. Each receiver supports a worldwide range of broadcast frequencies, including the FM 64-109MHz band, the AM 504-1750kHz band, and the short-wave (SW) 2.3-28.5MHz band, thereby enabling a receiver-based single radio design to meet the global market. demand.
James Labsberry, vice president and general manager of broadcast products at Silicon Labs, said: "The Silicon Labs Si48xx multi-band receiver family is based on an innovative 'single-chip radio' architecture that helps turn radio manufacturers to simplify and reduce board design and manufacturing. Labor costs, and reduce the number of devices by more than 80%. The new rotary receiver uses patented low-IF digital architecture, digital core and audio adjustment technology, the above technology has been used in our advanced radio IC products, and the world's top audio Product brand adoption."
Price and availability
The Si4825/27/36 multi-band receiver is available in a small 16-lead SOIC package for cost-effective single-sided PCB design and easy wire processing. The new receiver is now in volume production and samples are available. At 10,000 purchases, the unit prices for the Si4825, Si4827, and Si4836 ranged from $1.56, $1.76, and $1.66, respectively. To make the design of the radio system simpler, Silicon Labs also offers a demonstration board for each receiver product for $50.
Why the Glass wall Curtain LED display can lead the fashion of outdoor media?
The LED Glass curtain display appeared as an sudden emergence on the outdoor media market.
With the advantages of encapsulation technology, high brightness, wide viewing angle, adjustable screen area and easy installation, The transparent LED Glass Display has gradually replaced the traditional billboards, light boxed, etc., And become the high-profile new force for outdoor advertising media. At the same time, a small pitch is applicable to the Glass Wall Led Screen and led glass screen for window. There`re various types of Led Display products suitable for glass wall and glass window, such as Transparent Led display and LED strip curtain screen. As if, indoor and outdoor led curtain wall display has become a leading industry for led display market
