1300 Henley Court Pullman, WA 99163 509.334.6306 www.digilentinc.com FMC-HDMI Reference Manual Revised September 3, 2014 This manual applies to the FMC-HDMI rev. D Overview The FPGA Mezzanine Card High-Definition Multimedia Interface (FMC-HDMI) peripheral board enables developers to add HDMI input ports to field-programmable gate array (FPGA) based systems. The FMC-HDMI provides a development platform for customers to utilize high-definition image capturing for use with image processing applications. Features include: (2x) HDMI Type A Receptacles HDMI Receiver (ADV7611) HDMI Buffer (AD8195) On-board EDID EEPROM Male FMC LPC connector for digital signals Compatible with a wide range of VADJ voltages (1.8V 3.3V) The FMC-HDMI. 1 Functional Description The FMC-HDMI card contains two HDMI input ports. The first port, HDMI1, contains an ADI ADV7611 Receiver and outputs a decoded, level translated digital video signal to the FMC connector. The second port, HDMI2, contains an ADI AD8195 Buffer and outputs an HDMI-encoded signal to the FMC connector, leaving the system board to decode the signal (either in the FPGA or an external receiver). The appropriateness of the HDMI port depends entirely on the application. For instance, although HDMI2 does not decode the signal, it outputs to a smaller number of pins (14 instead of 36), which is useful in designs with limited input availability. Since the decoding must be done on the connected system board, the circuitry must support HDMI-type signaling that is TMDS. For example, Xilinx FPGA families support the TMDS 33 input standard in 3.3V- powered I/O banks. Copyright Digilent, Inc. All rights reserved.

FMC-HDMI Reference Manual 1.1 HDMI1: Analog Devices ADV7611 Receiver An Analog Devices ADV7611 Receiver decodes the signal on HDMI1. This low power, 165 MHz receiver supports formats up to UXGA 60Hz at 8 bit at 161 MHz. It has been tested at WUXGA (1080p) 60Hz at 148.5 MHz. The 2 receiver provides an audio output port for audio extracted from the HDMI signal in the following formats: I S, S/PDIF, and Direct Stream Transfer (DST). It also features an advanced mute controller. The ADV7611 Receiver contains several other features, such as a CEC 1.4-compatible controller for consumer device remote control and discovery and EDID (Extended Display Identification Data) RAM.
