As the industry's first dark HDMITM (High-Definition Multimedia InterfaceTM) with integrated CEC controller and analog interface, the ADV7604 delivers 1080p video features while delivering 12-bit depth while achieving Energy Star-class power efficiency. The color HDMI receiver is matched to four 170 MHz 12-bit ADCs to achieve dark precision on the analog interface when only 8 or 10 bit depths are available. This high level of integration eliminates up to five components, reducing HDTV's material cost and power consumption while delivering 1080p video performance, low standby power, seamless operation and perfect HDMI reception.
According to the latest report from market research firm In-Stat, 95% of digital TVs shipped worldwide in 2008 are equipped with HDMI interfaces. It can be said that in the field of consumer electronics, HDMI is already the standard interface and is the king of the market. According to In-Stat analysts, the most noteworthy consumer electronics products in the future are portable devices such as video recorders, digital cameras, portable media players (PMPs), etc. Manufacturers of such products are interested in introducing the HDMI interface. HDMI equipment shipments are expected to increase by 23% annually between 2009 and 2012.
Bill Bucklen, director of advanced television divisions at Analog Devices, said: "With the rapid development of the consumer electronics market, especially integrated entertainment electronic systems, HDMI now involves almost all consumer electronics devices that play high-definition content. ADI has consistently maintained a foothold in the market. Demand, constantly committed to the research and innovation of HDMI technology to reduce the cost and complexity of the consumer experience while providing consumers with the best end-user experience."
According to the latest research data from the Consumer Electronics Association (CEA), 89% of households want their next-generation TVs to be more energy efficient. However, only 25% of TV models are able to meet the Environmental Protection Agency's (EPA) latest Energy Star 3.0 specification, which came into effect on November 1, 2008, requiring TV and DVD players to consume from 3 The tile is reduced to 1 watt. The traditional HDTV design requires the main system chip, the digital zoom chip, to remain powered up in the system standby state, and to 'wake up' the TV once it receives the remote control signal. However, the digital zoom chip typically consumes more than 1 watt of standby power, which will not meet the new Energy Star standard. By integrating CEC buffering and its control program directly into the drivers of the HDMI interface, the ADV7604 helps designers achieve 1 watt or less of standby power to meet the new Energy Star 3.0 specification. In standby mode, only a small portion of the circuitry on the ADV7604 chip needs to be powered up to wait for CEC commands, while the rest of the HDTV system does not have to consume power.
In addition to the energy-saving advantages, the ADV7604 eliminates the cost of add-on components, including a discrete analog-to-digital converter, CEC controller, analog multiplexer, HDMI receiver, and HDMI multiplexer. Components may delay product launch or result in a significant cost redesign of the system to meet ENERGY STAR's power consumption or system budget.
Supply and quotation
The ADV7604 dual analog interface and HDMI receiver are fabricated in an advanced CMOS process and feature a 260-Ball BGA (ball grid array) surface-lead lead-free package with an operating temperature range of -40°C to +85°C. At 10,000-piece quantities, each piece is priced at $7.95. Samples of the ADV7604 are currently available and are expected to be in volume production in February 2009.
