Intel Arria 10 FPGA User Manual

Control Description
fXTAL Shows the calculated internal fixed-frequency crystal, based on the serial port
register values.
Default Sets the frequency for the oscillator associated with the active tab back to its
default value. This can also be accomplished by power cycling the board.
Set New Freq Sets the programmable oscillator frequency for the selected clock to the value in
the Target frequency control for the programmable oscillators. Frequency
changes might take several milliseconds to take effect. You might see glitches on
the clock during this time. Altera recommends resetting the FPGA logic after
changing frequencies.
Each Si5338 tab for U26 and U14 display the same GUI controls for each clock
generators. Each tab allows for separate control. The Si5338 is capable of synthesizing
four independent user-programmable clock frequencies up to 350 MHz and select
frequencies up to 710 MHz.
