Analog Devices Inc. recently introduced one of the industry's smallest, lowest power HDMI(TM) v1.4 transmitter ICs with integrated de-interlacing and on-chip CEC (Consumer Electronics Control) for low-cost small multimedia devices Perfect HD (High Definition) video performance and easy interconnection. The 150 MHz, ultra-low-power HDMI 1.4 transmitter with built-in de-interlacing, the Advantiv(R) ADV7541, converts 480i/p and 1080i interlaced output to 1080p progressive format, enabling portable multimedia devices to be delivered to home theaters The system provides full HD resolution. Compared to similar products, the HDMI 1.4 transmitter ADV7541 reduces standby power by 150 times and size (3.75 mm × 3.75 mm × 0.65 mm) by 10%, extending ADI's Advantiv advanced TV solution to digital cameras. And ultra-thin, low-power design fields such as digital SLR cameras, camcorders, game consoles, media players and mobile devices.

George Diniz, product line manager for video transmitters at Analog Devices, said: "As the world's smallest, thinnest, low-power HDMI 1.4 transmitter with built-in de-interlacing, the ADV7541 gives designers 1080p HD video and audio transmission on mobile devices. A complete solution that provides designers with a complete solution for bridging the gap between handheld multimedia devices and 1080p HD home entertainment systems with interlaced-progressive video conversion of the 480i and 1080i.
This highly integrated HDMI 1.4 transmitter integrates de-interlacing modules, CEC controllers, level shifters and microcontrollers, enabling designers to accelerate CEC and HDMI development, reduce development and manufacturing costs, and reduce time-to-market. In addition, because it reduces power consumption and size, and eliminates the need for external memory, the ADV7541 also enables engineers to develop low-power designs that can use thinner batteries and are less expensive.
The ADV7541 is validated for compatibility testing and is pin and software compatible with older video products such as the low-power HDMI transmitter ADV7521NK and the low-power HDMI transmitter with built-in CEC, supporting industry-leading connectivity standards such as HDMI (supports xvColor(TM) )). The HDMI Transmitter fully supports S/PDIF (Sony/Philips Digital Interface Format) audio formats for compressed audio such as Dolby Digital(R) and DTS(R), and 2-channel I2S audio for stereo transmission at sample rates up to 192 kHz format. The HDMI 1.4 Transmitter ADV7541 has the option of adding embedded support for HDCP 1.3 (High-bandwidth Digital Content Protection) processing for secure transmission of protected content.
