The small size HDMI 1.4a receiver supports 3D video in portables

HDMI, simplified A/V interface for the user and complex enough for the designer is gaining lot more depth in adoption across the portable devices with audio/video display. The interface which is analog requires HDMI receiver to receive the signal. Analog Device Inc. (ADI) has added a new HDMI receiver (supports HDMI 1.4a version), which consumes less power and less space compared to other in the market. The 3D video format supporting chips ADV7611 is a 165-MHz HDMI receiver and the ADV7612 is a 225-MHz, dual-port HDMI receiver with Xpressview fast switching technology to switch between HDMI-enabled devices in less than one second while supporting High Definition performance. As claimed by ADI ADV7611 (10 mm x 10 mm x 1.6 mm) and ADV7612 (14 mm x 14 mm x 1.6 mm) offer a 50 percent smaller footprint and a 25 percent reduction in power consumption for designs with 720p and 1080p resolutions. Some of the applications named by ADI include ultra-slim HTIB (home theater-in-a-box) systems, projectors, AVRs (audio/video receivers), HBR (high-bit-rate) TVs, matrix switches and sound bar speaker systems.

The HDMI 1.4 compliant receivers from other vendors noticed include SiI9233A HDMI 1.4 Receiver from Silicon Image and TDA19977B, a three input HDMI 1.4a compliant receiver from NXP Semiconductor.

Some of the HDMI receiver chips are still 1.3 version compliant they include GM69010H from ST Microelectronics, ANX9011 from Analogix Semiconductor and R8J66030FT HDMI receiver from Renesas
