Control
Description
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.
