HSMI 1.3-compatible devices from ADI

Analog Devices Inc. (ADI) continues to expand its line of HDMI interface ICs with the availability of HDMI v1.3-compatible multiplexer, receiver and transmitter circuits. The company's portfolio of HDMI components now includes devices that address the increasing consumer demand for HD content in multimedia products ranging from 1080p "deep color" HDTVs to low-power portable applications, including digital video and still cameras, portable media players and cellphones.

The new multiplexers, receiver and transmitters support the updated HDMI v1.3 standard, which defines the delivery of uncompressed HD content using a single cable to transmit super-high-quality video and audio.

For large-screen TVs
The AD8196 and AD8197 are said to be the industry's first buffered multiplexers to support 1080p "deep color" technology defined by the HDMI v1.3 specification. Deep color technology increases HDMI's data rate to 2.25Gbps, allowing the transmission and display of more than a billion colors. The resulting palette provides dazzling levels of detail and color depth supported by next-generation CE products, such as the newest game consoles. The new multiplexers also feature proprietary technology that allows them to equalize more than 20m of HDMI v1.3-compliant cable, affording consumers the flexible location of their TVs and home entertainment components without loss of video.

The AD9388A single chip, advanced TV interface combines an integrated dual-port HDMI v1.3 receiver with an analog interface that can digitize high-quality video from HD and legacy inputs. This new advanced TV interface supports multiple analog and HDMI v1.3 inputs to enable HDTV connections to VCRs, STBs, DVD players/recorders, game consoles, A/V receivers and digital video recorders. The AD9388A also includes on-chip adaptive cable equalization that ensures signal integrity for cable lengths up to 30m, while advanced audio muting prevents "pops" and "clicks" on the audio output.

For portable multimedia
The AD9387 tiny, low-power HDMI v1.3 transmitter is specifically designed for portable multimedia applications and supports HD video up to 1080i resolution. As HD formats migrate to handheld CE, end users will be able to create a high-definition network by viewing, recording and sharing HD content using personal video recorders, digital still cameras and other portable multimedia devices that can be connected to their HDTVs or home A/V equipment.

The AD9387 is the first low-power transmitter for video-enabled portable CE that meets HDMI v1.3 specifications, the company said. Optimized for high-quality video formats from 720p to 1080i, the transmitter supports both Sony/Philips digital interface (S/PDIF) and 8-channel I?S audio recording formats and transmits either stereo or 7.1-channel surround audio at 192kHz. This enables digital video cameras, cellphones and other handheld electronics to carry stereo linear pulse-code modulation (LPCM) audio or compressed audio, including Dolby Digital, DTS and THX. The AD9387 consumes 100mW of power at 80MHz and 20?W during power down, a 55 percent to 90 percent reduction as compared to other transmitters. A version of the new transmitter, the AD9387NK, further reduces cost and system design complexity by allowing for external implementation of HDCP keys.

Availability and pricing
The AD8196 (56-lead LFCSP) and AD8197 (100-lead LQFP) multiplexers are available for sampling with production availability scheduled this month. Pricing is $2.75 for AD8196 and $4.95 for AD8197. The AD9388A receiver (144-lead LQFP) is available for sampling with production availability scheduled April 2007. Pricing is $9.96. The AD9387 80MHz transmitter (64-pin LFCSP BGA) will be available for sampling this month with production availability scheduled in March 2007. Pricing is $4.86. The AD9387NK 80MHz transmitter (64-pin LFCSP BGA) is available for sampling with production availability scheduled next month. Pricing is $4.39. Prices are in 1,000 quantities.
