Table 2. EEPROM pre-programmed content.
The EEPROM can be freely re-written through the J4 header holes and 6-pin Pmod cable. During EEPROM
programming, power to the EEPROM is provided by pin 6 of J4, so make sure there is no HDMI cable plugged in at
the same time.
Below are the pin-outs from the AD8195 Buffer and other HDMI2 port signals to the FMC connector:

Table 3. HDMI2-FMC pin mapping.
WARNING: VADJ must be 3.3V to properly use the buffer on HDMI2. The TX_EN pin is held low by default, so the
buffer is disabled on power-up. With the buffer disabled, VADJ can be in the range of (1.8V-3.3V).
Note: For more information on the AD8195, see ADI datasheets available online
2.3 FMC Support
The FMC-HDMI uses a Samtec ASP-134604-01 low pin-count male connector as the main connector for digital
signals. The board fully conforms to the VITA 57.1 specs. The connector supports the full range of 1.8V-3.3V bank
supply voltages (VADJ).
The EEPROM with designator IC2 (see board schematic) serves as the IPMI EEPROM, providing hardware definition
information. For more information, consult the VITA 57.1 specs.
