Analog Devices Inc. introduces what it claims as the industry's first 3GHz HDMI (High-Definition Multimedia Interface) receiver for advanced television solutions. This new dual input receiver incorporates HDMI specification version 1.4a that support 3D display resolutions and extended colorimetry.

Unlike 2.25GHz ICs, Analog Devices' ADV7619 3GHz is effective for next-generation home entertainment AV (audio/video) systems that must support the higher data rates required for emerging 3D and HD sports, movie and broadcast content.

The 3GHz receiver enables home- and pro-AV designers to deliver the full benefits of 3D and HD video formats by meeting demanding performance requirements, including 3D 1080p at 60Hz for more realistic fast motion sports content, and 4K x 2K (4,000 x 2,000 pixels), for the high-end resolution used by digital cinemas, which at four times the resolution of 1080p, is considered by industry experts to be the next frontier in home theater displays.

A member of Analog Devices' Advantiv advanced TV solutions portfolio, the ADV7619 is a highly-integrated, single-chip, dual-port 3GHz receive solution that delivers the required HDMI and fast switching performance needed to quickly bring compelling new products to market, including HTIB (home theater-in-a-box) systems, AVRs (AV receivers), HBR (high-bit-rate) TVs, matrix switches and sound bar speaker systems.

According to recent a In-Stat research, HDMI has continued as the dominant interface in CE devices, particularly DTVs, Blu-ray and DVD players and recorders, AV receivers, and game consoles.

"3D and 4K x 2K resolutions are the future of HD video, and supporting those resolutions with advanced video ICs will be paramount," said Brian O'Rourke, principal analyst, digital entertainment at In-Stat. "Next-generation, 3GHz-capable HDMI receivers, such as Analog Device's ADV7619, enable designs to achieve the increased performance of 3GHz, while ensuring backward compatibility with existing AV designs."

3GHz data transmission puts extraordinary challenges on a HDMI receiver to operate with cables of differing quality and lengths. Unlike 2.25GHz receivers, the ADV7619 implements Analog Devices' adaptive equalization technology with automatic adjustment to provide the best 3GHz receive performance across a wide spectrum of sources, cables and input signal speed.

"The ADV7619 is the first 3GHz receiver of its kind to resolve the complex analog signal processing challenges required to bridge the gap between 2.25 to 3GHz," said Charles O'Roark, product line director, digital video products of Analog Devices. "Broadcasters, movie makers, and even YouTube, are already generating 3D-HD and 4K-HD video content. Yet, AV systems are not capable of displaying such high-quality HD video content using traditional 2.25GHz receivers. With support for HDMI 1.4a technology and 3GHz connectivity, the ADV7619 offers a fundamental shift in AV designs, enabling designers to turn pro- and home-AV systems into 3D- and 4K-HD entertainment hubs."
