Adv7842 is a high-quality single chip, 2:1 multi-channel HDMI ™ Receiver and graphics digitizer with integrated multi format video decoder. Adv7842 contains a dual input hdmi1 4 compatible receiver, supporting all HD TV formats up to 1080p, with display resolution up to uxga (1600 at 60Hz) × 1200)。
Adv7842 integrates X-ray on both input HDMI ports ™ Fast switching. Using analog devices, the hardware based HDCP engine minimizes software overhead, and xpressview technology allows fast switching between any HDMI input port in less than 1 second. Adv7842 supports all mandatory hdmi1 43D TV format, except for all HDTV formats up to 1080p, 36 bit deep color.
Adv7842 also integrates an hdmiv1 4cec controller, which supports function discovery and control (CDC) function. Adv7842 provides a flexible audio output port for audio data decoded from HDMI stream. Support HDMI audio format, including super audio CD (SACD) provided through DSD and HBr. Each HDMI port has a dedicated 5V detection and hot plug assertion pin. The HDMI receiver also includes an integrated equalizer to ensure robust operation for a 30 meter cable length. The HDMI receiver has audio functions, such as mute controller, which can prevent external noise in the audio output.
The multi format 3D comb filter decoder supports the conversion of pal, NTSC and SECAM standards into digital itu-rbt in the form of composite or S-Video input signals. 656 format. Adv7842 can process CVBS and RGB signals defined by the standard at the same time, thus enabling and coverage functions.
Adv7842 contains a main component processor (CP), which can process YPbPr and RGB component formats, including RGB graphics. The CP also processes video signals from the HDMI receiver. Adv7842 can operate in dual HDMI and analog input modes, allowing fast switching between ADCs and HDMI.
Adv7842 supports decoding component RGB / YPbPr video signals into digital YCbCr or RGB pixel output streams. Support for component video includes 525I, 625i, 525P, 625p, 720p, 1080i, 1080p, and 1250i standards, as well as many other SMPTE and HD standards.
Adv7842 supports graphics digitization. Adv7842 can digitize RGB graphics signal from VGA to uxga rate and convert it into digital RGB or YCbCr pixel output stream. Internal EDID can be used for one graphics port.
Adv7842 is manufactured by CMOS process and adopts 17mm × 17mm, 256 ball, BGA, surface mount, ROHS compatible package, and in the temperature range of − 10 ° C to + 70 ° C.
