Norwood, Mass.Analog Devices Inc. has added transmitters, receivers and multiplexers to its line of High-Definition Multimedia Interface (HDMI) ICs that are designed to deliver high-definition video and audio content from DVD players, set-top boxes, cameras and gaming consoles to advanced televisions.
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. For more on HDMI, click here: www.hdmi.org.
ADI's latest devices are mutually compatible and have all completed rigorous testing to ensure they meet the official HDMI Compliance Test Specification.
The HDMI transmitters and receivers support HDMI v1.2a signals up to UXGA resolutions (1600 x 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.
The 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 picture loss.
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.
The AD9889B and AD9389B transmitters offer designers the flexibility of selecting between internal (AD9389B) and external (AD9889B) high bandwidth digital content protection (HDCP) keys, which protect the integrity of the transmissions to prevent unauthorized copying of protected content.
The ADV7441, ADV7443 and AD9388 are single-chip receivers that 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 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.
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.
In quantities of 1,000, transmitter prices are as follows: the AD9889, $4.73; AD9389, $5.37; AD9889B, $5.16; and AD9389B, $5.65
In quantities of 1,000, the AD8190 and AD8191 multiplexers cost $2.50 and $4.75, respectively.
