Deep Color HDMI Receiver Enhances HDTV Performance and Energy Star Compliance
Analog Devices introduced the industry's first Deep Color HDMITM (High Definition Multimedia InterfaceTM) receiver integrated with a Consumer Electronics Control (CEC) controller and analog interface. Designed to provide 1080p video performance at Energy Star-levels of power efficiency, the ADV7604 Deep Color HDMI receiver with CEC matches a 12-bit Deep Color HDMI receiver with three 170-MHz, 12-bit analog-to-digital converters (ADCs), enabling Deep Color accuracy on the analog interface, while competitive components are still operating at only 8-bit or 10-bit color depth. This high level of integration can eliminate up to five components to reduce HDTV bill-of-material and power consumption costs, while delivering 1080p video performance, low standby power, seamless operation, and flawless HDMI reception.
The new HDMI receiver's on-chip support for high-bandwidth digital content protection (HDCP) processing and integrated software driver ensure that authentication checks for unauthorized recording take place seamlessly and without delay. The ADV7604 and its software driver have been thoroughly tested during HDCP PlugFests and by completing HDCP- and HDMI-compliance testing, providing designers with a certified repeater software driver that can be easily ported to various controllers.
The ADV7604 single-chip, analog graphics digitizer with integrated 4:1 multiplexed input Deep Color HDMI receiver and on-board CEC controller supports all HDTV formats up to 1080p and is capable of digitizing analog RGB display resolutions up to UXGA (1600 × 1200 at 60 Hz). The ADV7604 HDMI inputs have high-performance cable equalizers, providing the highest picture quality over cable lengths of up to 30 meters. The new, proprietary, on-chip DPLL (digital PLL) delivers ultralow video- and audio-clock jitter, improving receiver performance and easing printed circuit board (PCB) layout and signal integrity management when interfacing high-speed video buses to downstream devices.
The ADV7604 analog interface enables conversion of component RGB and YPrPb video signals into a digital YCrCb or RGB pixel output stream. The HDMI receiver supports a wide range of component video standards, including 525i up to 1080p and 1250i, as well as many other high definition and Society of Motion Picture and Television Engineers (SMPTE) standards. The ADV7604 provides complete audio support for eight channels of I2S audio, S/PDIF (Sony/Philips Digital Interface Format) digital audio output, and SACD (Super Audio CD) and compressed SACD support with Direct Stream Digital (DSD) and Direct Stream Transfer (DST) output interfaces, respectively.
The HDMI receiver also supports High Bit Rate (HBR) audio streaming to allow recovery (and downstream processing) of compressed lossless audio formats, including Dolby® TrueHD and DTS-HD Master AudioTM or DTS-HDTM High Resolution Audio. The ADV7604 supports global analog video connections, including the D-Terminal (U.S.) and D1-D5 Terminal (Japan) Component Video connectors and SCART (Europe) Component Video connector. Using ADI's complete set of software drivers, designers are able to easily integrate the ADV7604 into any application. For more information, please visit http://www.analog.com/pr/ADV7604.
