ADV7541 HDMI transmitter

From Analog Devices Inc. comes the ADV7541 HDMI v1.4 transmit IC with integrated de-interlacer and on-chip consumer electronics control (CEC), enabling small, low-cost multimedia devices to provide flawless high-definition video performance and easy connectivity.

The 150MHz, Advantiv ADV7541 ultralow-power HDMI 1.4 transmitter with de-interlacer converts 480i/p and 1080i interlaced output into a progressive 1080p format, enabling portable multimedia devices to provide full HD resolution to home theater systems. Offering 150x less standby power and a 10 percent smaller footprint (3.75mm x 3.75mm x 0. mm) than competing offerings, the ADV7541 HDMI 1.4 transmitter extends ADI's Advantiv advanced TV solutions portfolio to ultraslim, low-power designs, including digital still and DSLR cameras, camcorders, gaming consoles, media players, and mobile devices. Watch the ADV7541 video for more information on its features.

"As the world's smallest and thinnest low-power HDMI 1.4 transmitter with de-interlacer, the ADV7541 provides designers with a complete solution for 1080p video and audio transmission on mobile devices," said George Diniz, product line manager, video transmitter product line, ADI. "By delivering interlaced-to-progressive video conversion for both 480i and 1080i video formats, the ADV7541 offers designers a complete solution to bridge the gap between handheld multimedia designs and high definition 1080p home entertainment systems."

The HDMI 1.4 transmitter integrates the de-interlacer, CEC controller, level shifters and microcontroller, enabling designers to accelerate the CEC and HDMI development process, lower development and manufacturing costs, and decrease time-to-market. In addition to reducing power consumption and footprint, and eliminating external memory requirements, the ADV7541 enables engineers to develop lower power designs that can use smaller, lighter batteries at lower cost.

Validated through successful compliance testing, the ADV7541 is pin- and software-compatible with previous video products, including the ADV7521NK low-power HDMI transmitter and ADV7524 low-power HDMI transmitter with CEC, and incorporates the industry's leading connectivity standards including HDMI (supporting x.v.Color). The HDMI transmitter provides complete audio support of S/PDIF (Sony/Philips digital interface format) for compressed audio, including Dolby Digital and DTS; and two-channel I?S audio for transmitting stereo at sample rates up to 192kHz. With the optional inclusion of embedded support for HDCP 1.3 (high-bandwidth digital content protection) processing, the ADV7541 HDMI 1.4 transmitter allows the secure transmission of protected content.

The ADV7541 1.4 HDMI transmitter complements other ADI video transmitter components, including the ADV7390/1/2/3 low-power, chip-scale 10bit SD/HD video encoder and ADV7123 and ADV7125 triple high-speed video DACs.

The ADV7541 is available in 49-ball, WLCSP for $4.97.
