ADM-PA101 User Manual
3.5 FMC+ Interface
The FMC+ interface provides a high-performance and flexible front-panel interface through a range of
interchangeable industry standard IO modules.
The FMC+ interface adheres to VITA 57.4. The ADM-PA101 utilizes all possible FMC+ connectivity. This includes
all GPIO, all MGT links, and all clock capable IO.
FMC I2C signal (SCL and SDA at C30 and C31) are connected to the system monitor microcontroller. They are
used to determine operating voltage during startup and are not accessible to the user directly, but can be
accessed through the system monitor AVR2UTIL application.
Alpha Data provides a wide range of compatible FMC cards: Please see
, or contact [email protected] for more details.
It is possible for Alpha Data to pre-fit the ADM-PA101 with FMC+ modules. Please contact
[email protected] for full details and options.
The FMC Present signal (PRSNT_M2C_L at connector pin H2) is connected to the system monitor
microcontroller.
Note:
The ADM-PA101 supports only 1.5V and lower VADJ Voltages.
The ADM-PA101 provides additional keep out space in the FMC area to enable oversized FMC cards. This is
ideal for pluggable optical modules like QSFP-DD. See Alpha Data
for one example.
