There is a Silicon Labs I2C programmable quad clock generator Si5338A (U13) on-board. It's output frequencies can be programmed by using the are programmable via FPGA I2C -bus with address 0x70interface using slave device address 0x70 (corresponding I2C logic has to be implemented in FPGA design).
A 25 MHz (U14) oscillator is connected to pin 3 (IN3) and is used to generate the output clocks.Once running, the frequency and other parameters can be changed by programming the device using the I2C bus connected between the FPGA (master) and clock generator (slave). Logic needs to be generated inside the FPGA module to utilize I²C-bus correctly.

The on-board voltages of the TEC0330 FPGA board will be are powered up in order of a determined predefined sequence after the external voltages 12V on connector J5 and 3V3PCI on connector J1 are become available.
Core voltages and main supply voltages have to reach stable state and their "Power Good" - signals have to be asserted before other voltages like PL bank's I/O voltages can be powered up.
