On-board Si5338 programmable clock generator chip is used to generate clocks with 25 MHz oscillator as input connected to the pin IN3 as input reference. There is a I2C bus connected connection between the FPGA bank 14 (master) and clock generator chip (slave) which can be used to program output frequencies. See the reference design for more information.
