The digital data from the LM15851EVM board is quickly and easily captured with the TSW14J56EVM data
capture board. The TSW14J56EVM 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 HighSpeed 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 TSW14J56 device is automatically
configured to support a wide range of operating speeds of the LM15851EVM, but the device may not
cover the full operating range of the ADC device. Serial data rates (and corresponding sampling rates) of
10 Gb/s (4 GSPS) down to 1 Gb/s (1 GSPS) are supported.
In the following sections of this document, the LM15851EVM evaluation board is referred to as the EVM
and the LM15851 device is referred to as the ADC device.

Required Equipment
www.ti.com
The following equipment is not included in the EVM evaluation kit, but is required for evaluation of this
product:
• TSW14J56EVM data capture board plus 5-V power supply and mini-USB cable
• High-Speed Data Converter Pro software
• PC computer running Windows XP, 7, or 8
• One low-noise signal generator for analog input. TI recommends the following generators:
– HP HP8644B
– Rohde & Schwarz™ SMA100A
• Bandpass filter for analog input signal (500 MHz or desired frequency). The following filters are
recommended:
– Bandpass filter, greater than or equal to 60 dB harmonic attenuation, less than or equal to 5%
bandwidth, greater than 18-dBm power, less than 5 dB insertion loss
– Trilithic™ 5VH-series tunable BPF
– K&L Microwave™ BT-series tunable BPF
– TTE KC6 or KC7-series fixed BPF
• Signal-path cables, SMA or BNC (or both SMA and BNC)
By default, the LM15851EVM has an onboard clocking solution. A few small board modifications enable
external clocking. If external clocking is used, the following equipment is recommended.
• Two low-noise signal generators. TI recommends similar models to the an analog input source.
• Two bandpass filters for clock inputs. TI recommends filters similar to the analog-input path filter.
NOTE: For frequencies at 3100 MHz and below, the two clock sources must be set to the same
value. For frequencies above 3100 MHz, the clock source that is used to drive the
LMK04828 (labeled LMKCLK) must be half of the frequency used to drive the LM15851
sampling clock (labeled DEVCLK)

Submit Documentation Feedback
Copyright © 2014, Texas Instruments Incorporated
Install the High Speed Data Converter (HSDC) Pro Software
www.ti.com
3.1
Install the High Speed Data Converter (HSDC) Pro Software
Download the most recent version of the HSDC Pro software from www.ti.com/tool/dataconverterpro-sw.
Follow the installation instructions to install the software.
3.2
Install the Configuration GUI Software
1. Download the Configuration GUI software from the EVM tool folder at
http://www.ti.com/tool/LM15851EVM.
2. Extract files from the .zip file.
3. Run the setup.exe executable file and follow the instructions.
3.3
Connect the EVM and TSW14J56EVM
With the power off, connect the LM15851EVM to the TSW14J56EVM 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 TSW14J56EVM is in the off position. Connect the 5-V power
supply adapter to the TSW14J56EVM.
2. Confirm that the 5-V power supply for the LM15851EVM is turned off. Connect the 5-V power supply to
the power connector (the power connector that is the closest to the USB connector).
CAUTION
Do not turn on the power to any board. Powering up the boards in the incorrect
order could potentially cause damage to one of the boards.
3.5
Connect the Signal Generators to the EVM (RF Signal Off)
1. Connect a signal generator to the VIN input of the LM15851EVM 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
497.97MHz, 0 dBm.
If external Clocking is Used (Optional)
2. 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 4 GHz. For best
performance when using an RF signal generator, the power input to the CLK SMA connector must be
11 dBm (2.2 Vpp into 50 Ω) must be at least 4 dBm to function. Therefore, the signal generator must
increase above 11 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 11 dBm + 2 dB = 13 dBm.
3. Connect a signal generator to the LMKCLK input of the EVM through a bandpass filter. Configure the
signal generator to 2 GHz.
NOTE:
1.
2.
3.
At sampling frequencies less than 3100 MHz, the LMKCLK must be set to the same
frequency as the DEVCLK. For sampling frequencies above 3100 MHz, LMKCLK must
be set to half the frequency of the DEVCLK.
Frequency locking the input signal generators using the 10-MHz reference can also be
done if coherent sampling is desired. This is not required as HSDC Pro offers windowing
options for FFT analysis. Ensure that both clocking sources are locked together with a
10-MHz reference to ensure functionality.
Do not turn on the RF output of any signal generator at this time.

HSDC Pro Settings for Optional ADC Device Configuration
C.1
Changing the Number of Frames per Multi-Frame (K)
Changing the number of frames per multi-frame output by the JESD204 transmitter (ADC device) is
configured using the K parameter on the JESD204B tab in the Configuration GUI. This parameter must be
matched by the receiving device, but configuration of the K parameter of the receiver is not supported at
this time.
C.2
Customizing the EVM for Optional Clocking Support
By default, the LMX2581 is configured to generate the device clock with an onboard crystal oscillator and
the LMK04828 is used as a clock distribution and provides the system reference clock for the FPGA. The
EVM can be configured to use an external clock with the following steps (see Figure C-1):
1. Modify the Hardware:
(a) Remove C32 and C33. Populate C30 and C36.
(b) Remove C112 and C113. Populate C114 and C123.
2. Connect the Signal Generators:
(a) Connect the 10-MHz references between signal generators.
(b) Sig Gen 1 connects to DEVCLK. Set to Fclk = FDEVCLK.
(c) Sig Gen 2 connects to LMKCLK.
For FDEVCLK > 3100 MHz
FLMKCLK = FDEVCLK / 2 connects
For FDEVCLK < 3100 MHz, FLMKCLK = FDEVCLK
3. Program the GUI:
(a) In the EVM tab, set the Clock Source to External.
(b) Enter the Sampling Frequency (DEVCLK) in step 2(b).
