3GHz HDMI 5:2 cross point Transceiver with On-Screen Display
The HDMI receivers and transmitters in the ADV7625 support the reception and transmission of 3 GHz video formats up to 4k × 2k at 24 Hz/25 Hz/30 Hz, in addition to all mandatory HDMI 3D TV formats. The receivers and transmitters also provide support for THX® Media Director™.
Each HDMI receiver features an integrated equalizer that ensures robust operation of the interface with cable lengths up to 30 meters. The HDMI receivers share a 768-byte volatile extended display identification data (EDID) memory, which can facilitate one or two EDIDs, one for each receiver. Each HDMI port features dedicated 5 V detect and Hot Plug™ assert pins.
Each HDMI transmitter supports audio return channel (ARC) and features an integrated HDMI CEC controller that supports capability discovery and control (CDC).
The ADV7625 offers two audio output ports and two audio input ports. Each audio port supports the extraction and insertion of up to eight channels of audio data out of or into the HDMI streams. HDMI audio formats, including I2S, S/PDIF, direct stream digital (DSD), and high bit rate (HBR) audio are supported.
The ADV7625 features a TTL pixel port input that facilitates the reception of digital video data from an analog front-end decoder (for example, the ADV7180, ADV7181D, or ADV7842).
The ADV7625 has an integrated on-screen display (OSD) generator that enables the creation and control of high quality character- and icon-based system status and control displays. The OSD can be overlaid on 3 GHz video formats and 3D video. Customers who are interested in using OSD are provided with Blimp, the Analog Devices OSD development tool.
The ADV7625 is provided in a space-saving, 260-ball, 15 mm × 15 mm CSP_BGA surface-mount, RoHS-compliant package and is specified over the 0°C to 70°C temperature range.

This product has been released to the market. The data sheet contains all final specifications and operating conditions. For new designs, ADI recommends utilization of these products.
The evaluation board provides a Blackfin® ADSP-BF524 processor for system control. The ADSP-BF524 offers the potential to process audio (no audio software is included). The evaluation board includes software (firmware) that provides a serial command interface to control the board's functionality.
The EVAL-MELODY-5 is a comprehensive, integrated DSP and HDMI™ based development platform to facilitate the design and development of AVRs, soundbars, multichannel gaming headphones and powered speakers. The hardware incorporates latest DSP and HDMI products and is supported by CrossCore® Eclipse-based tools and the user friendly GUI-based SigmaStudio™ for SHARC®. The development board is an optimized hardware design that utilizes two fourth generation SHARC processor, the ADSP-21489, running at 400MHz and the new 4K resolution UHD capable crosspoint transceiver.
All control and housekeeping functions on the EVAL-MELODY-5 platform are efficiently performed by a Blackfin® BF524 processor.
Dolby Atmos® and DTS:X decoders have been implemented and are certified by Dolby and DTS respectively at the IC level to reduce uncertainty regarding product certification. The UHD capabilities of the ADV7625 crosspoint transceiver support a 4K video pass through and allow HDMI embedded audio to be extracted, processed and either reinserted or rendered locally.
The hardware design allows cascading multiple SHARC processors to facilitate the development of systems that require more than two DSPs. The two DSPs execute Dolby Atmos and DTS:X decoders and the board may be interfaced to additional DSP processors for executing post processing routines. The ADV7625 HDMI Transceiver passes through video while extracting the embedded audio for processing by the DSPs and then optionally re-inserting the audio into the HDMI output stream.
Based on ADI’s award-winning SigmaStudio for SigmaDSP® digital signal processor tool, the SigmaStudio for SHARC tool is a programming, development and real-time tuning software environment that enables developers to graphically design and program audio applications for SHARC processors using an extensive, optimized library of more than 100 pre-built audio algorithms such as filtering, mixing, and dynamics processing, as well as basic low-level DSP functions and control blocks. SigmaStudio runs on a PC connected to the EVAL-MELODY-5 platform and helps software and audio engineers shorten their design times. SigmaStudio is unique in that it has proven to be friendly to audio designers while also meeting the needs of software engineers. It is easy to create software schematics by dragging the required modules from a library of about 100 different modules that are available. The CrossCore® Eclipse-based tools provide an easy development environment and are in used in conjunction with the SigmaStudio for SHARC.
