Multi-input HDMI receiver accelerates HD-TV design

The TDA19978 HDMI receiver from NXP Semiconductors has four independent inputs to eliminate the need for an external HDMI switch, which saves system costs and accelerates product-design cycles.

Each input also has its own integrated Extended Display Identification Data (EDID) memory, which eliminates the need for external EDID memory and associated switches.

In addition, this HDMI-1.3 compliant receiver has 12-bit colour depth and largegamut colour-space support for improved video performance. It also delivers an enhanced audio experience due to a highbit- rate audio path and Direct Stream Transport (DST), enabling transport of audio streams such as DTS-HD™ or Dolby TrueHD™.

The TDA19978 supports all high-definition formats including 60Hz 1080p HDTV and 1600 x 1200 UXGA PC display resolutions.

In applications that use the Consumer Electronics Control (CEC) protocol that forms an optional part of the HDMI specification, the TDA19978 partners closely with the NXP TDA9950 CEC controller to enhance the functionality and interoperability of devices connected in a HDMI system.
