Analog Devices Inc. introduced what the company claims is the industry's first Deep Color HDMI transmitter to integrate a consumer electronic control (CEC) controller and buffer for high-definition (HD) audio/video devices.

The highly-integrated Advantiv ADV7510 Deep Color HDMI transmitter with CEC reduces component count, eases design complexity and shortens time-to-market for audio/video receivers, Blu-ray DVD players, high-performance STBs, digital video recorders, computers and video game consoles, the company said. Unlike competitive offerings that require a separate CEC controller, the ADV7510's on-chip controller speeds the CEC and HDMI certification process, while reducing board space by 20 percent. Backed by ADI's field-tested software driver and HDMI pre-certification testing, the ADV7510 further shortens time-to-market.

Lower development, manufacturing cost
"CEC is now a must-have feature for today's entertainment systems. By eliminating the external CEC microcontroller, the ADV7510 lets designers deliver proven, high-performance A/V equipment without the additional field testing normally required to ensure compatibility," said Bill Bucklen, director of ADI's advanced TV segment. "The ADV7510 enables proven, high-performance A/V equipment with 12bit Deep Color operation and 1,080p connectivity in a single-chip solution that lowers development and manufacturing cost."

ADI says the ADV7510 is the industry's first transmitter with integrated CEC to incorporate HDMI's Deep Color capability into HDTV designs with resolutions up to 1,080p. Deep Color increases the number of colors that can be displayed on video devices, allowing millions of distinct colors to be displayed. This allows gradual changes in hue or brightness across a picture appear smoother and more lifelike. By increasing the color depth from 8bits to 12bits per color, the ADV7510's Deep Color performance enhances color vividness and accuracy of video delivery and display. The new HDMI transmitter also supports x.v.Color, which increases the range of available colors to render the most realistic images possible when playing digital video content.

Supported by ADI's integrated CEC controller and software driver, the ADV7510 ensures connectivity between the system and multiple audio and video components that support the HDMI standard. With the inclusion of on-chip high-bandwidth digital content protection (HDCP) processing, the ADV7510 implements the functions of HDMI repeater applications that prevent unauthorized recording, ensuring HDCP authentication without delay. The ADV7510 helps further reduce system cost by incorporating features such as an I?C master for extended display identification data reading and 5V tolerant I/Os that support I?C and Hot Plug Detect.

The ADV7510 supports S/PDIF (Sony/Philips Digital Interface Format) for linear pulse code modulation or compressed audio including Dolby Digital, DTS and THX. With eight-channel I?S audio support, the transmitter enables either stereo or 7.1-channel surround sound audio up to 768kHz. In addition, up to eight channels of direct stream digital audio are available to support the latest HD audio standards.

The ADV7510 is compatible with other ADI components in the advanced TV signal chain, including the ADV7441A HMDI receiver with 10bit integrated, multiformat standard-definition (SD) TV video decoder; SD/HD analog component video digitizer and two-input HDMI receiver; ADV7390"93 video encoders and AD8190/1/2/5/6/7A/7B HDMI/DVI switches and buffers with equalized inputs.

ADI's HDMI pre-testing labs are located in Tokyo, Japan; Beijing, China; Taipei, Taiwan; and Greensboro, North Carolina, USA; this is where customers can evaluate their equipment performance prior to submission to HDMI Compliance Testing. ADI's HDMI technologies are validated through successful compliance testing at authorized HDMI Compliance test centers.

The ADV7510 Deep Color HDMI transmitter is now available in production quantities. The ADV7510 is fabricated on an advanced CMOS process and is available in a 14mm x 14mm 100-lead LQFP package. It is specified over the -25C to +85C temperature range. The ADV7510 is priced at $7.59 per unit in 1,000-piece quantities.
