Unlike 2.25-GHz ICs, ADI’s ADV7619 3-GHz, dual-port receiver 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 3-GHz 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 60 Hz 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 theatre displays.
A member of ADI’s Advantiv® advanced TV solutions portfolio, the ADV7619 is a highly-integrated, single-chip, dual-port 3-GHz receive solution that delivers the required HDMI and fast switching performance needed to quickly bring compelling new products to market, including HTIB (home theatre-in-a-box) systems, AVRs (AV receivers), HBR (high-bit-rate) TVs, matrix switches and sound bar speaker systems.
According to recent In-Stat research, , a leading semiconductor research firm, 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, In-Stat. “Next-generation, 3-GHz-capable HDMI receivers, such as Analog Device’s ADV7619, enable designs to achieve the increased performance of 3 GHz, while ensuring backward compatibility with existing AV designs.”
3-GHz data transmission puts extraordinary challenges on a HDMI receiver to operate with cables of differing quality and lengths. Unlike 2.25 GHz receivers, the ADV7619 implements ADI’s state-of-the-art adaptive equalisation 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 3-GHz receiver of its kind to resolve the complex analogue signal processing challenges required to bridge the gap between 2.25 to 3 GHz,” said Charles O’Roark, product line director, digital video products, 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 2.25 GHz 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.”
The 3-GHz receiver incorporates ADI’s proprietary XpressviewTM fast switching technology, which enables automatic switching between multiple HDMI-enabled AV systems in less than one second. The ADV7619 offers an on-chip CEC (consumer electronics component) controller, an integrated audio codec, support for HDCP (high-bandwidth digital content protection) 1.4 and complete audio support of S/PDIF (Sony/Philips digital interface format) for compressed audio, including Dolby Digital and DTS; and 2-channel I2S audio for transmitting stereo at sample rates up to 192 kHz. The ADV7619 allows for optional inclusion of embedded key support for HDCP 1.4 content protection.
