Low-Power HDMI receivers enhance audio/video system performance

NORWOOD, USA: Analog Devices Inc. (ADI) has announced the industry’s smallest, single-chip receivers to incorporate HDMI (High-Definition Multimedia Interface) specification version 1.4a support for 3-D display resolutions and extended colorimetry.

ADI’s ADV7611 low-power, 165-MHz receiver and the ADV7612 225-MHz, dual-port receiver with Xpressview fast switching technology enable A/V (audio/video) designers to deliver rich feature sets and HD performance traditionally reserved for higher priced entertainment systems.

Compared to competitive offerings, the ADV7611 (10x10x1.6mm) and ADV7612 (14x14x1.6mm) offer a 50 percent smaller footprint and a 25 percent reduction in power consumption for designs with 720p and 1080p resolutions. The receivers extend ADI’s Advantiv advanced TV solutions portfolio and are effective for power-sensitive, ultra-slim HTIB (home theater-in-a-box) systems, projectors, AVRs (audio/video receivers), HBR (high-bit-rate) TVs, matrix switches and sound bar speaker systems.

“Until today, designers of high-performance A/V portable devices and infotainment systems were forced to use multiple, higher-power components to offer system designs with feature-rich interfaces,” said Charles O’Roark, product line director, digital video products, Analog Devices.

“By incorporating ADI’s low-power receiver, HDMI technology, and a feature-rich A/V interface onto a single chip, designers can achieve an unequalled combination of performance and accuracy, while eliminating the power limitations that restrict portability and increase system design cost.”

The ADV7611 enables portable designers to achieve 1080p/60f display resolution with 24-bit color. For high-performance A/V systems, the ADV7612 offers 1080p/60f display resolution with up to 36-bit Deep Color and incorporates ADI’s proprietary Xpressview fast switching technology, which enables seamless, automatic switching between HDMI-enabled devices in less than one second. The receivers are available in automotive and industrial grades.

Each receiver features an on-chip CEC (consumer electronics component) controller, 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 ADV7612 allows for optional inclusion of embedded support for HDCP 1.4 content protection.

The receivers are compatible with other Analog Devices components, including the Advantiv advanced TV switches; Blackfin and SHARC processors; the SoundMAX portfolio of audio algorithms and codecs; and power management ICs.
