The default EVM configuration uses the LMK04828 clocking device to generate the sampling clock. There are two options to improve the clock noise performance. 1. To achieve the best performance, the LMK04828 can be bypassed in favor of an externally provided clock that is transformer coupled to the ADC. The clock must have very low noise and must use an external narrow pass-band filter to achieve optimal noise performance. The clock amplitude must be within the datasheet limits. See Section 5.1 for more information regarding this setup. 2. The LMK04828 can be used as a clock distributor by using an external clock as the input to the LMK04828. Filters should still be used on the clock to optimize the noise performance. See Section 5.1.2for more information regarding this setup. 3.2 Coherent Input Source A Rectangular window function can be applied to the captured data when the sample rate and the input frequency are set precisely to capture an integer number of cycles of the input frequency (sometimes called coherent frequency). This may yield better SNR results. The clock and analog inputs must be frequency locked (such as through 10-MHz references) in order to achieve coherency. 3.3 HSDC Pro Settings HSDC Pro has some settings that can help improve the performance measurements. These are highlighted in Table 4. Table 4. HSDC Pro Settings to Optimize Results HSDC Pro Feature Description Analysis Window (samples) Selects the number of samples to include in the selected test analysis. Collect more data to improve frequency resolution of FFT analysis. If more than 65,536 samples are required, the setting in the Data Capture Options will need to be increased to match this value. Data Windowing Function Select the desired windowing function applied to the data for FFT analysis. Select ‘Blackman’ when sampling a non-coherent input signal or ‘Rectangle’ when sampling a coherent input signal. Test Options → Notch Frequency Bins Select bins to be removed from the spectrum and back-filled with the average noise level. May also customize which Harmonics/Spurs are considered in SNR and THD calculations and select the method for calculating spur power. Test Options → Bandwidth Integration Markers Enable markers to narrow the Single-Tone FFT test analysis to a specific bandwidth. Data Capture Options → Capture Options Configure the number of contiguous samples per capture (capture depth). May also enable Continuous Capture and FFT Averaging.

There are three additional clocking options that the EVM supports. These options are described in sections Section 5.1.1 through Section 5.1.3: 5.1.1 External ADC Sampling Clock An external clock can be used as the sampling clock for the ADC. This clock can be provided through a transformer using the EXT_ADC_CLK connector (J6). For this option C47 and C48 need to be uninstalled and installed at R35 and R39. The LMK04828 must still be used to provide the device clock to the TSW14J56 and the SYSREF signals to both boards. This option will provide the best performance as long as the clock source has better phase-noise performance than the LMK04828. The source of the EXT ADC clock must be synchronized with the LMK04828. To accomplish this, send the 10-MHz reference output from the signal generator and connect it to J12 (CLKIN) of the ADS5XJ6XEVM. This will cause LED D6 to illuminate indicating the LMK VCXO source is locked to the external reference clock. The provided LMK configuration files will work in this mode as well. To turn off the ADC clock provided by the LMK04828 to reduce switching noise, click on the LMK04828 tab, then click on clock outputs tab, then select “Powerdown” for DCLK Type under Clock Out 2 and 3, as shown in Figure 9. Figure 9. Low Level View Tab 14 ADS5XJ6X Evaluation Module SLAU641D – June 2015 – Revised January 2016 Submit Documentation Feedback Copyright © 2015–2016, Texas Instruments Incorporated Alternate Hardware Configurations www.ti.com 5.1.2 External LMK04828 Clock (Clock Distribution Mode) The LMK04828 can be used as a clock distributor. In this case, the LMK04828 uses in input clock source from CLKIN SMA connector (J12). JP2 (XO_PWR) can be left open to turn off the onboard VCXO to avoid crosstalk. To use this mode, load the configuration file named "LMK_Config_External_Clock.cfg”. This mode allows generation of frequencies that are not possible with the LMK when using the on-board VCXO. 5.1.3 Clock Generator Using Onboard VCXO The LMK04828 is used as a clock generator using the onboard 122.88-MHz VCXO. JP2 must be shorted to turn on the onboard VCXO. The internal PLLs of the LMK04828 can be used with the onboard VCXO to generate the desired frequencies. To use this mode, load one of the configuration files named “LMK_Config_LMF_xxxx_yyyy_MSPS.cfg”, where xxxx corresponds to the LMFS settings of the JESD interface and yyyy corresponds to the desired ADC sampling rate. A 10-MHz signal can be brought into the CLKIN input to synchronize to external instruments. This is the board default mode of operation.
