Analog Devices, Inc. (ADI), an electronics manufacturer located in Norwood, Mass., unveils its smallest and thinnest low-power transmitters to incorporate “high-definition multimedia interface” (HDMI) version 1.4 specification support for 3-D display resolutions and extended colorimetry, the company says in a written statement.

With a 25 percent smaller footprint compared to other low-power transmitters, ADI’s low-power transmitters—the 80 MHzADV7525 and the 150 MHz ADV7526—enable mobile device designers to achieve new levels of miniaturization, flawless HD video performance and power efficiency, ADI says. They are compatible with the ADI receivers—the ADV7611 and ADV7612—which are among the industry’s smallest, lowest power receivers, the company adds.

Each device extends ADI’s Advantiv advanced television solutions portfolio by offering an on-chip 24-bit video interface that supports existing systems-on-chip (SOC) designs, further reducing time-to-market and design costs, ADI says. The ADV7525 and ADV7526 support HDTV formats up to 720p60f/1080i and 1080p/60f at 1.8 V, making them effective for ultra-slim, power-sensitive handheld designs, including mobile phones, gaming consoles, portable media players, mobile Internet devices, digital still and DSLR cameras and camcorders.

“By incorporating support for HDMI Version 1.4 specification’s 3-Ddisplay resolutions and extended colorimetry and a 24-bit video interface on a single chip, these transmitters are the first to close theHD performance gap between ultra-slim, multimedia devices and home entertainment systems,” said Charles O'Roark, product line director for Digital Video Products.

Complete with internal enhanced consumer electronic control (CEC) with expanded message buffer, 5-V tolerant I/Os and on-chip I[sup .2]Cmaster, the highly integrated, energy-saving transmitters provide designers with system-ready solutions that lower development and manufacturing costs across a wide range of HDMI-enabled devices, ADI says.

In addition, the ADV7525 and ADV7526 offer complete audio support of Sony/Philips digital interface format for compressed audio, including Dolby DigitalR and DTS; and 8-channel I2S audio for transmitting stereo at sample rates up to 192 kHz. With the inclusion of embedded support for HDCP 1.3 (high-bandwidth digital content protection) processing, the transmitters allow the secure transmission of protected content.
