Manual Software Adjustment

In general, the GUI software operates similar to the individual GUIs of the DAC38RF8x EVM and the
ADC32RFxx EVM. It is possible to operate in a manual mode following the procedure of the RF DAC and
RF ADC respectively; however, there are a few minor differences.

5.7.1

RF DAC Set-Up Conditions

The DAC PLL reference frequency is derived from the LMK VCO divided down outputs. This is the only
way to provide this reference; there is no option for external PLL reference.

5.7.2

RF ADC Set-Up Conditions

ADC SysRef is generated through the LMK device so its VCO must be set to the desired clocking
frequency.

Clock divider for the FPGA is calculated based on SerDes rate of the DAC.
