ML605 - What is the FMC_VIO_B_M2C power supply? What voltage does it supply?


ML605 documentation and schematics mention FMC_VIO_B_M2C. What does this power supply refer to? And what voltage does it supply to the Virtex-6 FPGA?


FMC_VIO_B_M2C is the I/O rail which supplies the voltage to Bank 12 of the Virtex-6 device on the ML605. This is shown in the ML605 schematics, and also in Table 1-3 of UG534, the ML605 Hardware User Guide:

Figure 1 - Table 1-3 Voltage Rails
Figure 1 - Table 1-3 Voltage Rails

This I/O rail has a 2.5V voltage applied to it.

This power for Bank 12 actually comes from the card which is plugged into the FMC connector of the ML605 board. This setup adheres to the VITA 57.1 FMC spec.
