The company states that 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.
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 adaptive equalisation technology with automatic adjustment to provide the best 3 GHz receive performance across a wide spectrum of sources, cables and input signal speed.
The 3 GHz receiver incorporates ADI’s proprietary Xpressview 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.
