The ADV7513 is a 165 MHz, High-Definition Multimedia Interface (HDMI®) transmitter that is ideal for DVD players/ recorders, digital set-top boxes, A/V receivers, gaming consoles, and PCs.
The digital video interface contains an HDMI v1.4/DVI v1.0-compatible transmitter and supports all HDTV formats. The ADV7513 supports HDMI v1.4-specific features, including 3D video. The ADV7513 also supports x.v.Color™, high bit rate (HBR) audio, and the programmable auxiliary video information (AVI) InfoFrame features. With the inclusion of HDCP, the ADV7513 allows the secure transmission of protected content as specified by the HDCP v1.4 protocol.
The ADV7513 supports both S/PDIF and 8-channel I2S audio. Its high fidelity 8-channel I2S interface can transmit either stereo or 7.1 surround audio up to 768 kHz. The S/PDIF interface can carry compressed audio, including Dolby® Digital, DTS®, and THX®. Fabricated in an advanced CMOS process, the ADV7513 is provided in a 64-lead LQFP surface-mount plastic package with exposed pad and is specified over the −25℃ to +85℃ temperature range.

EVAL-ADV7612-7511視頻評估板
The Advantiv® EVAL-ADV7612-7511 video evaluation board (AVEB) is a low cost solution for evaluating the performance of the ADV7612 HDMI receiver and/or the ADV7511 HDMI transmitter.
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.
This evaluation board is available in two options.
With HDCP support (EVAL-ADV7612-7511), available only to licensees of HDCP
Without HDCP support (EVAL-ADV7612-7511P)
EVAL-ADV7612-7511視頻評估板主要特性:
2 HDMI inputs, 1 HDMI output
PC communication via RS-232 or USB interface
Jumperable signal paths for audio and video (jumpers can be removed and signals connected in a different manner)
EQUIPMENT NEEDED
Computer with RS-232 (or USB) I/O to accomplish the following:
Send scripts to the board’s command line interface
Send commands to the board’s repeater software and view software output
Control the board via Advantiv video evaluation software (AVES) application
Update the board’s firmware (if desired or necessary)
