Analog Devices introduced what it called the industry’s first 3-gigahertz HDMI receiver to support advanced 3-D and HD video content.
SAN FRANCISCO—Aiming to offer a silicon solution for next- generation home audio/video systems that must support the higher data rates required for emerging 3-D and HD sports, movie and broadcast content, Analog Devices Inc. (ADI) Wednesday (May 4) introduced what it called the industry’s first 3-gigahertz HDMI receiver for advanced television solutions.
The new dual input receiver supports High-Definition Multimedia Interface (HDMI) specification version 1.4a support, 3-D display resolutions and extended colorimetry, said ADI (Norwood, Mass.). According to Lie Dou, ADI product marketing manager for digital video products, unlike 2.26 GHz ICs, ADI’s ADV7619 3-GHz, dual-port receiver, meets performance requirements for 3-D 1080p at 60 Hz for more realistic fast motion sports content and 4K x 2K—4,000 by 2,000 pixels—for the high-end resolution used by digital cinemas, by some industry experts to be the next frontier in home theater displays.
The ADV7619, a member of ADI’s Advantiv TV solutions portfolio, is a single-chip solution that delivers the HDMI and fast switching performance needed to quickly bring new products to market, including home theater-in-a-box systems, AV receivers, high-bit-rate TVs, matrix switches and sound bar speaker systems, according to ADI.
According to market research firm In-Stat, , HDMI has continued as the dominant interface in consumer electronics devices, particularly DTVs, Blu-ray and DVD players and recorders, AV receivers, and game consoles.
Brian O’Rourke, principal analyst for digital entertainment at In-Stat said 3-D and 4K x 2K resolutions are the future of HD video. “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,” O’Rourke said.
The ADV7619 incorporates ADI’s proprietary Xpressview fast switching technology, which enables automatic switching between multiple HDMI-enabled AV systems in less than one second, according to the firm. 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 company said.
The ADV7619 also allows for optional inclusion of embedded key support for HDCP 1.4 content protection, ADI said.
The ADV7619 is compatible with other Analog Devices components, including Advantiv switches, Blackfin and SHARC processors, ADI’s SoundMAX portfolio of audio algorithms and codecs, and ADI’s power-management ICs, the company said.
The ADV7619 is sampling now and will be in full production availability in June, priced at $7.09 per unit in 1,000 unit quantities, ADI said. The devices are available in 14 mm by 14 mm thermally enhanced thin quad flat pack (TQFP) packages, ADI said.
