ADV7850:  Complete AV Front-End

Product Details

Product Status:Recommended for New Designs

The ADV7850 is a high quality, single chip, multiformat video decoder graphics digitizer with an integrated 4:1 multiplexed HDMI® receiver.

This 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 HDMI output stream. SCART and overlay functionality are enabled by the ability of the ADV7850 to process CVBS and standard definition RGB signals simultaneously.

The ADV7850 contains one main component processor (CP) that processes YPrPb and RGB component formats, including RGB graphics. The ADV7850 can operate in quad HDMI and analog input mode, thus allowing for fast switching between the analog video inputs and HDMI.

The ADV7850 supports the decoding of a component RGB/ YPrPb video signal into a HDMI 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 ADV7850 supports graphics digitization. The ADV7850 is capable of digitizing RGB graphics signals from VGA to UXGA rates and converting them into an HDMI output stream. Internal EDID RAM is available for one graphics port.

The ADV7850 incorporates a quad input HDMI-compatible receiver that supports all HDTV formats up to 3D 1080p 60 Hz and 2160P 24 Hz.

The ADV7850 supports full HDCP decryption with internal key storage. The ADV7850 features HDCP authentication on all ports simultaneously. The feature allows fast switching between HDMI ports. Sync measurements and status monitoring are also available for all HDMI ports. 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 flag, that prevents audible extraneous noise in the audio output.

In addition, the HDMI receiver incorporates internal EDID support, which can be made available in full power, powerdown, and power-off modes. An internal regulator supplies external EDID memory from the HDMI 5 V signal in poweroff mode.

The ADV7850 incorporates Xpressview™ fast switching on all HDMI input ports. Using the Analog Devices, Inc., hardwarebased HDCP engine that minimizes software overhead, Xpressview technology allows fast switching between any two HDMI input ports in less than 1 second.

The ADV7850 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, DST, and HBR are supported.

The ADV7850 also features the single mode audio return channel (ARC) feature. ARC simplifies cabling by combining upstream audio capability in a conventional HDMI cable.

The stereo audio ADC converts analog audio inputs and provides the data to the back end via the HDMI interface. The stereo audio DAC receives I2S data from the back end and converts it to analog audio output. The audio output is available as both high impedance and a driven output, which is suitable for driving headphones directly.

Fabricated in an advanced CMOS process, the ADV7850 is provided in a 19 mm × 19 mm, 425-ball, CSP_BGA, surfacemount, RoHS-compliant package, and is specified over the −20°C to +70°C temperature range.
