3 / 28 page ADV7842 Rev. B | Page 3 of 28 GENERAL DESCRIPTION The ADV7842 is a high quality, single-chip, 2:1 multiplexed HDMI™ receiver and graphics digitizer with an integrated multiformat video decoder. The ADV7842 incorporates a dual input HDMI 1.4-compatible receiver that supports all HDTV formats up to 1080p and display resolutions up to UXGA (1600 × 1200 at 60 Hz). The ADV7842 incorporates Xpressview™ fast switching on both input HDMI ports. Using the Analog Devices, Inc., hardware- based HDCP engine that minimizes software overhead, Xpressview technology allows fast switching between any HDMI input ports in less than 1 second. The ADV7842 supports all mandatory HDMI 1.4 3D TV formats in addition to all HDTV formats up to 1080p, 36-bit Deep Color. The ADV7842 also integrates an HDMI v1.4 CEC controller that supports the capability discovery and control (CDC) feature. The ADV7842 offers a flexible audio output port for the audio data decoded from the HDMI stream. HDMI audio formats, including super audio CD (SACD) via DSD and HBR are supported. Each HDMI port has dedicated 5 V detect and hot plug assert pins. The HDMI receiver also includes an integrated equalizer that ensures robust operation of the interface with cable lengths up to 30 meters. The HDMI receiver has advanced audio functionality, such as a mute controller, that prevents audible extraneous noise in the audio output. The multiformat 3D comb filter decoder supports the conversion of PAL, NTSC, and SECAM standards in the form of a composite or an S-Video input signal into a digital ITU-R BT.656 format. SCART and overlay functionality are enabled by the ability of the ADV7842 to process CVBS and standard definition RGB signals simultaneously. The ADV7842 contains one main component processor (CP) that processes YPbPr and RGB component formats, including RGB graphics. The CP also processes the video signals from the HDMI receiver. The ADV7842 can operate in dual HDMI and analog input mode, thus allowing for fast switching between the ADCs and HDMI. The ADV7842 supports the decoding of a component RGB/ YPbPr video signal into a digital YCbCr or RGB pixel output stream. The support for component video includes 525i, 625i, 525p, 625p, 720p, 1080i, 1080p, and 1250i standards, as well as many other SMPTE and HD standards. The ADV7842 supports graphics digitization. The ADV7842 is capable of digitizing RGB graphics signals from VGA to UXGA rates and converting them into a digital RGB or YCbCr pixel output stream. Internal EDID is available for one graphic port. Fabricated in an advanced CMOS process, the ADV7842 is provided in a 17 mm × 17 mm, 256-ball, BGA, surface-mount, RoHS-compliant package and is specified over the −10°C to +70°C temperature range. |
