Introduction
Chapter 1
SLAU796–July 2020
Introduction
The TSW12QJ1600EVM is an evaluation board used to evaluate ADC12QJ1600 analog-to-digital
converters (ADC) from Texas Instruments with different front end options. The ADC12QJ1600 is a quad
channel, 12-bit ADC, capable of operating at sampling rates up to 1.6 Giga- samples per second (GSPS)
with four analog input channels. This design has two ADC12QJ1600 devices on the same PCB, this
design can be used to demonstrate multiple ADC synchronization, deterministic latency and test the
performance of the ADC with various front end options (AC coupled transformer, DC coupled option with
LMH32401) The design also demonstrate how clocking scheme can be simplified by daisy-chaining PLL
refout from one ADC to other ADC. Eliminating the need to clock distribution chip usually needed by JESD
devices. The TSW12QJ1600EVM output data is transmitted over a standard JESD204C high-speed serial
interface. This evaluation board also includes the following important features
• Transformer-coupled signal input network allowing a single-ended signal source from 10 MHz to
4 GHz. Option to bypass the transformer and use DC coupled differential inputs
• LM95233 temperature sensor
• High-speed serial data output over a High Pin Count FMC interface connector
NOTE: To improve signal routing quality, serial lanes are mapped differently with respect to the
standard FMC VITA-57 signal mapping.
• Device register programming through USB connector and FTDI USB-to-SPI bus translator with an
option to program through the FMC+ connector

The digital data from the TSW12QJ1600EVM board is quickly and easily captured with the
TSW14J58EVM data capture boards.

Introduction
NOTE: The TSW14J58EVM can only be used be used for JMODES 8 at a maximum sampling rate
of 1GSPS.
The TSW14J58EVM 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.

2.2 Required Equipment
The following equipment and documents are included in the EVM evaluation kit:
• Evaluation board (EVM)
• Mini-USB cable
• Power cable
The following equipment is not included in the EVM evaluation kit, but is required for evaluation of this
product:
• TSW14J58EVM data capture board and related items
• PC computer running Microsoft®Windows®7, or 10
• One low-noise signal generator for providing a reference signal for the ADC PLL. ONLY need with
external reference clocking option is desired. TI recommends the following generators:
– Rohde & Schwarz®SMA100B
– Rohde & Schwarz®SMA100A
• One low-noise signal generator for analog input. TI recommends the following generators:
– Rohde & Schwarz®SMA100B
– Rohde & Schwarz®SMA100A
• Bandpass filter for analog input signal (97 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 to SMP or BNC (or both SMA and BNC)
By default, the TSW12QJ1600EVM is configured to use a 50-MHz onboard crystal oscillator to provide
reference input to the ADC PLL which is used to generate the sampling clock to the ADC (In the GUI this
option is labeled as " OnBoard 50M Ref to ADC PLL"). A few small board modifications allow the direct
external sampling clock option (In the GUI this option is labeled as "Ext Ref to ADC PLL").

Setup Procedure
Figure 3-1. EVM Test Setup
NOTE: The HSDC Pro software must be installed before connecting the TSW14J58EVM to the PC
for the first time.
3.1 Install the High Speed Data Converter (HSDC) Pro Software
1. 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.
2. Download and copy all the INI files required to the HSDCpro directory from the TSW12QJ1600EVM
web page on ti.com. The INI files should be copied to following location C:\Program Files (x86)\Texas
Instruments\High Speed Data Converter Pro\14J58 Details\ADC files
3.2 Install the Configuration GUI Software
1. Download the Configuration GUI software from the TI.com software page .
2. Extract files from the .zip file.
3. Run the executable file (setup.exe), and follow the instructions.

Setup Procedure
3.3 Connect the EVM and TSW14J58EVM
With the power off, connect the TSW12QJ1600EVM (with the daughter card already mounted on base
board) to the TSW14J58EVM 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 TSW14J58EVM is in the off position. Connect the power cable to
a 6-V DC (minimum 4 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 6 V. Connect the
power cable to the EVM power connector.
2. Confirm that the power switch for the power supply of the TSW12QJ1600EVM is in the off position.
Connect the power cable to a 5-V DC (minimum 2.5 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 5 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 any of the input labeled J2–J9 on the daughter card connected to the
TSW12QJ1600EVM through a bandpass filter and at the SMP 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 97 MHz, 0 dBm.
When onboard 50-MHz crystal oscillator is used as a reference for the ADC PLL (Default):
a. By default, the EVM is set to use the onboard 50-MHz crystal oscillator to supply the 50-MHz reference
to the ADC PLL.
b. Skip this step for default ("OnBoard 50M Ref to ADC PLL ") EVM setup. This step should only be
followed when "Ext Ref to ADC PLL mode is desired. The reference clock signal for the ADC PLL of
desired frequency (50 MHz to 500 MHz) is applied at the SMP connector EXT CLK (J2). Set the output
power to approximately 6–9 dBm.
NOTE: Do not turn on the RF output of any signal generator at this time.
3.6 Turn On the TSW14J58EVM Power and Connect to the PC
1. Turn on the power switch of the TSW14J58EVM.
2. Connect a mini-USB cable and USB 3 cable from the PC to the TSW14J58EVM.
3. If this is the first time connecting the TSW14J58EVM to the PC, follow the on-screen instructions to
automatically install the device drivers. TSW14J58EVM user's guide for specific instructions.
3.7 Turn On the TSW12QJ1600EVM Power Supplies and Connect to the PC
1. Turn on the 5-V power supply to power up the EVM.
2. Connect the EVM to the PC with the mini-USB cable.
3.8 Turn On the Signal Generator RF Outputs
Turn on the RF signal output of the signal generator connected to INAP. If Ext Ref to ADC PLL clocking
option is used, turn on the RF signal outputs connected to EXT CLK
