Quad-input HDMI 1.3 receiver improves HDTV viewing

Eindhoven, The Netherlands — NXP has developed a HDMI 1.3 receiver chip, the TDA19978HL, to improve the quality of audio and video performance of HDTVs by combining 12-bit deep color and extended gamut, as well as high bit rate (HBR) and direct stream transport audio formats.

NXP says the TDA19978HL is industry's first HDMI 1.3 receiver with four inputs, which eliminates the need for an external HDMI switch. The integrated receiver chip also reduces the overall cost of an HDTV by embedding EDID memory for each of the four independent HDMI inputs.

With a maximum link frequency of 2.3 GHz, the TDA19978 quad-input HDM I1.3 receiver supports all HDTV formats including 1080p/60 Hz TV and the UXGA (1600 x 1200) at 60 Hz PC display resolutions. The TDA19978 is housed in a small, low-pin count HLQFP144 package with three levels of power management, as well as optional software drivers.

The TDA19978 quad-input HDMI1.3 receiver will be showcased at NXP's booth (Hall 1.1, Booth 213) at IFA 2007 in Berlin, Germany, August 31 to September 5.
