3.9 Launch the DAC39RF10EVM GUI and Program the DAC EVM
The DAC39RF10EVM configuration GUI is installed separately from the HSDC Pro installation and is a stand-
alone GUI.
The max clock rate supported by DAC39RF10EVM is 10240 MHz
Figure 3-3
and
Figure 3-4
of the panel organize the configuration into device and EVM features with user-friendly controls and a low-level
tab for directly configuring the registers. The EVM has three configurable devices, namely the DAC39RF10,
LMX1204 and LMK04828. The register map for each device is provided in the device data sheet (DAC39RF10,
LMK04828B, and LMX1204, respectively).
1. Lauch the DAC39RF10EVM GUI.
2. Select the LMX->DACCLK | LMX/LMK->FPGA as the clock source.
3. Enter Clk Freq 10240 MHz.
4. Select JMODE0 for JMODE option.
5. Select 64b66b for Encoding option.
6. The other option can be left to default settings.
7. Click Program Devices (Note: This action overwrites any previous device register settings.)
3.10 Programming the NCO
The following steps are only needed when DAC is programmed to JMODE 1 to 7. For JMODE0 the NCO
configuration can be skipped to the section
greater than or equal to 2 and interpolation factor is also set to greater than or equal to 2, the NCO(numerically
controlled oscillator) can be used to mix I/Q baseband signal to generate a higher output frequency signal from
the output of the DAC.
Table 3-2
describes the relationship of interpolation factor and number of streams to number of DUCs ( Digital up
converter) that can be used.
