Chorus 4 is a single-chip solution, which integrates four previously separate chips to deliver significant cost and energy consumption savings.<\/p>\n<p>Chorus 4 is the fourth generation chip from Frontier Silicon. The chip is designed to encourage the continued advance of digital radio around the world by supporting all major global digital radio standards. Chorus 4 provides solutions for multiple devices, including consumer radios, the automotive aftermarket and, for the first time, smartphones and tablets. The company\u2019s previous solutions have already powered over 20 million digital radios worldwide.<\/p>\n<p>The key features and benefits of Chorus 4 are:<\/p>\n<ul>\n<li>Low cost, single chip solution: integration of RF front-end, baseband, application processor and DAC (\u201cfour chips in one\u201d) delivers significant cost savings which enable high quality, entry-level price point digital radios<\/li>\n<li>Ultra-low power consumption &#8211; one month\u2019s listening for 5-6 hours a day on a portable radio with four D cell batteries (comparable to FM performance)<\/li>\n<li>Multiple solutions for portable and table-top radios, smart-device docks, wireless speakers, hand-held receivers, sound-bars and audio systems<\/li>\n<li>Automotive aftermarket &#8211; solutions for head units, integrated convertors and low cost adapters<\/li>\n<li>Smart devices &#8211; enables digital radio solutions for mobile phones and tablets<\/li>\n<li>Bluetooth connectivity &#8211; connecting smart devices and digital radios to enable hybrid radio (with interactivity and additional content delivered via IP), music streaming and remote control<\/li>\n<li>Integrated service guides &#8211; new software will enable listeners to select stations from a single list of digital and analogue stations regardless of platform<\/li>\n<li>Multiple radio standards &#8211; including support for AM, FM, DAB, DAB+, HD Radio and DRM<\/li>\n<\/ul>\n<p>Digital Tick compliant &#8211; Chorus 4 solutions meet all technology requirements of the UK minimum specifications for both domestic and automotive digital radio devices.<br \/>\nFrontier Silicon CEO, Anthony Sethill, said<\/p>\n<blockquote><p>\u201cChorus 4 represents a step change for the digital radio market. After ten years of development on this and previous solutions, we now have our fourth generation chip \u2013 an integrated, single chip offering enhanced functionality, lower cost and significantly greater energy efficiency. Chorus 4 will power multiple devices, including low cost automotive adapters and devices with Bluetooth connectivity. For the first time, digital radio in mass deployment smartphones will become a viable proposition. As a multi-standard chip, Chorus 4 will address emerging opportunities around the world. I look forward to working closely with broadcasters, transmission operators and device manufacturing partners to address these exciting opportunities.\u201d<\/p><\/blockquote>\n<p>About Frontier Silicon Limited<\/p>\n<p>Frontier Silicon is the world\u2019s leading supplier of integrated circuits and modules for digital radio and connected audio products.
