4.3. Control On-Board Clock through Clock Controller GUI
The Clock Controller GUI can change the on-board programmable PLLs to a large
range of customized frequency. The instructions to run Clock Controller GUI are stated
in the Run BTS GUI section. You can also start it using the BTS GUI icon “Clock”.
The clock controller communicates with the system Intel MAX 10 device through a 10-
pin JTAG header J3 or Micro-USB connector J10. Then, system Intel MAX 10 controls
these programmable clock parts through a 2-wire I
2
C bus.
Note:
You cannot run the stand-alone Clock Controller GUI application when the BTS or
Power Monitor GUI is running at the same time.

ZL30733
The output frequency of ZL30733 is from 0.5 Hz to 750 MHz. It can generate up to 10
differential outputs with a total of 5 output frequency families. The following sections
describe the Clock Controller buttons.
Read
Reads the current frequency setting for the oscillator associated with the active tab.
Set
Sets the programmable oscillator frequency for the selected clock to the value in the
OUTx
output controls for ZL30733. Frequency changes might take several milliseconds
to take effect. You might see glitches on the clock during this time. Intel recommends
resetting the FPGA logic after changing frequencies.
