- HDMI transmitters, receivers and multiplexers enable the delivery of high-definition video and audio content from DVD players, set-top boxes, cameras and gaming consoles to advanced televisions.

USA (08/14/2006) - Beverly Hills, Calif. - HDTV Conference, August 15-16--Analog Devices, Inc. (NYSE: ADI) a global leader in high-performance semiconductors whose audio and video signal processing technology is powering some of the world’s leading consumer electronics brands, is extending its line of High-Definition Multimedia Interface™ (HDMI™) ICs to offer customers the industry’s broadest portfolio of HDMI transmitters, receivers and multiplexers. These highly integrated display interface ICs are designed to deliver optimal performance, the highest resolution video, and easy connectivity to next-generation televisions that support the HDMI standard. HDMI is a widely used digital interface standard that delivers uncompressed high-definition (HD) content via a single cable, allowing consumers a simple, seamless connection to view and hear the highest-quality images and sound on their HDTVs. The devices announced today are mutually compatible and have all completed rigorous testing to ensure they meet the official HDMI Compliance Test Specification. ADI’s HDMI technologies have been validated through successful compliance testing at authorized HDMI test centers.

“High-definition content is driving the growth of consumer applications in advanced television and next-generation consumer equipment, and ADI is committed to enhancing the HD user experience,” said Martin Cotter, product line director of Advanced TV Strategy, Analog Devices. “We work closely with customers designing a variety of audio and video product to ensure sound and images are of the highest quality, because preserving quality among all connected equipment in the digital home is critical to the HD user experience.”

All of ADI’s HDMI transmitters and receivers support HDMI v1.2a signals up to UXGA resolutions (1600 × 1200 at 60 Hz) and DVI (digital video interface) v1.0. In addition, the receivers feature on-chip adaptive cable equalization to ensure signal integrity for cable lengths up to 30 meters at full HD (1080p) resolution. ADI’s HDMI multiplexer products leverage an advanced equalizer technology, which allows consumers to position their HD equipment up to 20 meters away from the television without incurring HDMI signal degradation that can result in loss of picture.

HDMI Transmitters
Designed into DVD players, digital video recorders (DVRs), cable and satellite set-top boxes, digital cameras, and gaming consoles, the AD9889B and AD9389B transmitters forward HD video and audio signals to corresponding receivers in televisions, computer monitors and display projection systems. The devices support up to 165 MHz and are pin-compatible with ADI’s recently released AD9889 and AD9389 transmitters.

Both of the HDMI transmitters announced today offer designers the flexibility of selecting between internal (AD9389B) or external (AD9889B) high bandwidth digital content protection (HDCP) keys, which protect the integrity of the transmissions to prevent unauthorized copying of protected content. By offering both internal and external keys, ADI is able to meet varying system feature requirements, save valuable implementation time and lower overall system cost.

HDMI Receivers
The ADV7441, ADV7443 and AD9388 are single-chip receivers that integrate all the functions necessary to receive and digitize high-quality video from HD and legacy inputs. The ADV7441 and ADV7443 integrate a multi-format video decoder and graphic digitizer with a dual input HDMI receiver. The video decoder supports NTSC/PAL/SECAM formats with excellent sensitivity for weak RF (radio frequency) signal conditions. The AD9388 integrates a 12-channel analog input component digitizer with a dual-input HDMI receiver. With the capability to support multiple analog and HDMI inputs, the AD9388 will enable connection to VCRs, set-top-boxes, DVD players/recorders, game consoles, A/V receivers and DVRs. The three devices are also pin-compatible, enabling television manufacturers to utilize a single platform layout for multiple designs.

The devices also support S/PDIF, and I2S audio up to 7.1-surround sound at 192 kHz. The AD9889B and AD9389B also support additional functionality in HDMI v1.3.

HDMI Multiplexers
ADI’s HDMI multiplexers allow designers of advanced televisions to include up to two (AD8190) or four (AD8191) HDMI inputs in their systems so end users can connect multiple DVD players/recorders, DVRs, game consoles and set-top boxes to their televisions. Unlike existing HDMI multiplexers, ADI’s products leverage an advanced equalizer technology, which enables consumers to connect the highest-resolution (1080p) HD equipment over more than 20 meters of cable. As a result, end users can position their HD sources farther away from the television without incurring HDMI signal degradation that can result in loss of picture. Until now, performance of available HDMI multiplexers limited consumers of HD content to 5 meters or less of HDMI connecting cable. The devices’ high-speed inputs are fully buffered and 50-ohm terminated, which reduces part count, simplifies board layout and improves signal integrity at higher data rates.

ADI’s HDMI Pre-Testing Labs
In addition, ADI is also announcing the recent opening of HDMI pre-testing labs in Beijing and Taipei (in addition to its original lab in Greensboro, North Carolina). Work is underway to open a fourth HDMI pre-testing lab in Tokyo in October. These local labs are available for ADI’s customers to evaluate their equipment performance prior to submission for HDMI Compliance Testing. ADI is providing these local HDMI pre-testing labs for its customers to help improve their time-to-market by ensuring all requirements listed in the HDMI Compliance Test Specification will be met.
