Figure 3-2 and Figure 3-3 show the GUI open to the EVM tab and Control tab respectively. Tabs at the top 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 ADC12DJ5200RF,
LMK04828, LMK61E2, and LMX2594. The register map for each device is provided in the device data sheet
(
ADC12DJ5200RF 10.4-GSPS Single Channel or 5.2-GSPS Dual Channel, 12-bit, RF , LMK0482xB Ultra Low-
Noise JESD204B Cmplnt Clck Jitter Cleaner w/ Dual Loop PLLs , and LMX2594 15-GHz Wideband PLLatinum™
RF Synthesizer , respectively).
1. Open the ADC12DJ5200RFEVM GUI.
2. Select the external clock as the clock source.
3. Enter Fs = 5200 MHz MSPS as the external Fs selection.
4. Select JMODE1 for the sampling and Calibration mode.
5. Click
Program Clocks and ADC (Note: This action will overwrite any previous device register settings.)
6. The Reference frequency required by the EVM is shown under indicator Reference Clock.
3.10 Calibrate the ADC Device on the EVM
Figure 3-3. Configuration GUI ADC Control
1. With the EVM GUI open on the PC, navigate to the Control tab.
2. To calibrate the ADC, click Cal Triggered/Running once, then click it again. This will stop and re-start the
Calibration engine.
Note
This calibrate button executes a calibration sequence that is required for full performance. This
calibration is performed automatically during the
Section 3.9 step but must be performed again,
any time the sampling rate changes, after significant temperature change of the ADC, or after
exiting the power-down mode. See the ADC12DJ5200RF device data sheet, (
SLVSEN9 ) for
details regarding the necessary calibration sequence.
3. To enable background calibration, use the following steps:
