Introduction
Figure 1-1. EVM Orientation
The digital data from the ADC12DJ5200RFEVM board is quickly and easily captured with the
TSW14J57EVM data capture boards.
NOTE: The TSW14J57EVM cannot be used for JMODES (30 to 39) that use 64b/66b encoding, or
serial rates above 15 Gbps.
The TSW14J57EVM captures the high-speed serial data, decodes the data, stores the data in memory,
and then uploads it to a connected PC through a USB interface for analysis. The High-Speed Data
Converter Pro (HSDC Pro) software on the PC communicates with the hardware and processes the data.
With proper hardware selection in the HSDC Pro software, the TSW14J57 device is automatically
configured to support a wide range of operating speeds of the ADC12DJ5200RFEVM, but the device may
not cover the full operating range of the ADC device. Serial data rates of 15 Gbps down to 1 Gbps are
supported.

Setup Procedure
3.3 Connect the EVM and TSW14J57EVM
With the power off, connect the ADC12DJ5200RFEVM to the TSW14J57EVM through the FMC connector
as shown in Figure 3-1. Ensure that the standoffs provide the proper height for robust connector
connections.
3.4 Connect the Power Supplies to the Boards (Power Off)
1. Confirm that the power switch on the TSW14J57EVM is in the off position. Connect the power cable to
a 12-V DC (minimum 3 A) power supply. Ensure the proper supply polarity by confirming that the outer
surface of the barrel connector is GND and the inner portion of the connector is 12 V. Connect the
power cable to the EVM power connector.
2. Confirm that the power switch for the ADC12DJ5200EVM's power supply is in the off position. Connect
the power cable to a 12-V DC (minimum 2 A) power supply. Ensure the proper supply polarity by
confirming that the outer surface of the barrel connector is GND and the inner portion of the connector
is 12 V. Connect the power cable to the EVM power connector.
CAUTION
Ensure the power connections to the EVMs are the correct polarity.
Failure to do so may result in immediate damage.
Leave the power switches in the off position until directed later.
3.5 Connect the Signal Generators to the EVM (RF Outputs Disabled Until Directed)
Connect a signal generator to the VIN input of the ADC12DJ5200RFEVM through a bandpass filter and
attenuator at the SMA connector. This must be a low-noise signal generator. TI recommends a Trilithic-
tunable bandpass filter to filter the signal from the generator. Configure the signal generator for 2897 MHz,
6 dBm.
When External Clocking is Used
a. Connect a signal generator to the DEVCLK input of the EVM through a bandpass filter. This signal
generator must be a low-noise signal generator. TI recommends a Trilithic-tunable bandpass filter to
filter the signal coming from the generator. Configure the signal generator for the desired clock
frequency in the range of 0.8 to 5.2 GHz. For best performance when using an RF signal generator,
the power input to the CLK SMA connector must be 9 dBm (2.2 Vpp into 50 Ω). The signal generator
must increase above 9 dB by an amount equal to any additional attenuation in the clock signal path,
such as the insertion loss of the bandpass filter. For example, if the filter insertion loss is 2 dB, the
signal generator must be set to 9 dBm + 2 dB = 11 dBm.
b. Connect a signal generator to the reference signal input of the EVM at REF CLK(J17). Configure the
signal generator for the desired (260MHz) clock frequency. Set the output power to approximately 6–9
dBm.
NOTE: 1. The Reference clock frequency can be obtained from the ADC12DJ5200RFEVM GUI.
Once the ADC12DJ5200EVM GUI is configured to the desired JMODE mode and clock
rate. The Reference Clock frequency required by the EVM is displayed on first page of
the GUI shown with red square in Figure 3-2
2. Ensure that the DEVCLK and Reference clock sources are frequency-locked using a
common 10-MHz reference to ensure functionality. Frequency locking the input signal
generator to the other generators can also be done if coherent sampling is desired.
3. Do not turn on the RF output of any signal generator at this time.
4. When using the ADC in single-input mode, the device uses both edges of DEVCLK for
sampling.

General problems
• Verify the test setup shown in Figure 3-1, and repeat the setup procedure as described in this
document.
• Check power supply to EVM and TSW14J57EVM. Verify that the power switch is in the on
position.
• Check signal and clock connections to EVM.
• Visually check the top and bottom sides of the board to verify that nothing looks discolored or
damaged.
• Ensure the board-to-board FMC+ connection is secure.
• Try pressing the CPU_RESET button on the TSW14J57EVM. Also try clicking Instrument
Options →Reset Board after changing the ADC configuration.
• Try power-cycling the external power supply to the EVM, and reprogram the LMK and ADC
devices.
TSW14J57 LEDs are not
correct
• Verify the settings of the configuration switches on the TSW14J57EVM.
• Verify that the clock going to the CLK input is connected and the appropriate LEDs are blinking.
• Verify that the ADC device internal registers are configured properly.
• If LEDs are not blinking, reprogram the ADC EVM devices.
• Try pressing the CPU_RESET button on the TSW14J57EVM.
• Try capturing data in HSDC Pro to force an LED status update
Configuration GUI is not
working properly
• Verify that the USB cable is plugged into the EVM and the PC.
• Check the computer device manager and verify that a USB serial device is recognized when
the EVM is connected to the PC.
• Verify that the green USB Status LED light in the top right corner of the GUI is lit. If it is not lit,
click the Reconnect FTDI button.
• Try restarting the configuration GUI.
Configuration GUI is not
able to connect to the EVM • Use the free FT_PROG software from FTDI chip and verify that the onboard FTDI chip is
programmed with the product description ADC12DJxx00RF .
HSDC Pro software is not
capturing good data or
analysis results are
incorrect.
• Verify that the TSW14J57EVM is properly connected to the PC with a mini-USB cable and that
the board serial number is properly identified by the HSDC software.
• Check that the proper ADC device mode is selected. The mode should match in HSDC Pro and
the ADC GUI.
• Check that the analysis parameters are properly configured.
HSDC Pro software gives a
time-out error when
capturing data
• Try to reprogram the LMK device and reset the JESD204 link.
• Verify that the ADC sampling rate is correctly set in the HSDC software.
• Try pressing the CPU_RESET button on the TSW14J57EVM. Also try clicking Instrument
Options →Reset Board after changing the ADC configuration. Try to recapture again.
• Select Instrument Options →Download Firmware and download
'TSW14J57RevE_16L_XCVR_ADCDDRDACBRAM.rbf'. Try to capture again.
Sub-optimal measured
performance
• Try clicking Cal Triggered/Running button 2× to re-calibrate the ADC in the current operating
conditions. It is located on the Control tab of the configuration GUI.
• Check that the spectral analysis parameters are properly configured.
• Verify that bandpass filters are used in the clock and input signal paths and that low-noise
signal sources are used.
