This user's guide describes the function and use of the ADC117x evaluation module (EVM). Included in
this document are a quick-start guide, jumper and connector descriptions, software description, and
alternate hardware configurations.
The ADC117xEVM is designed to evaluate the ADC1173, ADC1175, and ADC1175-50. The EVM
provides simple and minimal external components to reduce system cost and power consumption.
The following features apply to this EVM:
•8-bit, low-cost, low-power, high-speed CMOS interface ADC117x data converter
•Onboard oscillator or external source for sampling clock
•User-programmable, low-dropout (LDO) voltage regulator
•Level-shifting data buffer for ADC CMOS output
The ADC117xEVM is designed to work seamlessly with the TSW1400EVM, TI's CMOS and LVDS pattern
generator and data-capture board.
1.1Required Hardware
The following equipment is included in the EVM kit:
•ADC117xEVM
•Standard banana jack power supply cables
The following list of equipment are items that are not included in the EVM kit, but are items required for
optimal evaluation of this product:
•TSW1400EVM Data Capture Board, 5-VDC cable connector, and mini-USB cable
•Personal computer running Microsoft®Windows®XP or later.
This section details the EVM test procedure to obtain a valid data capture from the ADC117xEVM using
the TSW1400EVM capture card and HSDC Pro. This should be the starting point for all evaluations.
2.1Software Installation
HSDC Pro must be installed before beginning the evaluation. See Section 1.2 for a list of the required
software. Section 6 contains links to find the software on the TI website.
1. Download HSDC Pro from the TI website. The References section of this document contains the link to
find the software on the TI website.
2. Extract the files from the zip file.
3. Run setup.exe and follow the installation prompts.
2.2Hardware Setup Procedure
Figure 3 shows a typical test setup using the ADC117xEVM and the TSW1400EVM. This is the test setup
used for the quick-start procedure. The rest of the section describes the hardware setup steps for each
variant of the ADC117xEVM.

Figure 3. Typical Test Setup Using ADC117xEVM and TSW1400EVM
1. Connect the ADC117xEVM to the TSW1400EVM connecting pin 1 of the CMOS_INTERFACE (J1) to
pin 1 of ADC117xEVM output data (J1).
2. Connect the power cable to connector J12 (5 V IN) to the TSW1400EVM.
3. Connect the mini-USB cable to the USB connector (J5).
4. Turn on the power supply. Flip the power switch (SW7) to the ON position.
This setup procedure is performed for each variant of the ADC117xEVM.
2.2.2ADC1173EVM Setup
Set up the ADC1173EVM using the following steps:
1. Connect the banana jack power-supply cables to the EVM. Connect the red wire to +5 VDC of a power
supply, rated for at least 3 A, and to J4.Connect the black wire to J5 and to GND of the power supply.
2. Turn on the power supply.
3. Ensure JP2 is shunted to the 1-2 position to provide a 15-MHz clock signal to the ADC and CMOS
interface. To use an external clock source, provide an external 15-MHz, 1-dBm, clock signal to J3.
Shunt jumper JP2 to the 2-3 position.
4. Set the analog input signal generator to 4.44 MHz, +7 dBm.
5. Place a 4-MHz band-pass filter at the output of the analog input signal generator to reduce noise and
harmonics.
6. Connect the output of the band-pass filter to the analog input at J6.
Quick-Start Guide
2.2.2.1ADC1173EVM Evaluation
Use the following steps for ADC1173EVM evaluation:
1. Launch HSDC Pro by going to Start Menu → All Programs → Texas Instruments → High Speed Data
Converter Pro.
2. A prompt appears showing the TSW1400EVM as a connection. Click OK.
3. A dialog box informs you that there is no firmware loaded, click on the Select ADC box and choose
ADC1173_cmos. Select Yes when prompted to update the firmware.
4. Once the firmware has been loaded, enter "15M" in the ADC Output Data Rate field, and push enter
on the keyboard.
5. Click the Capture button. The results of the captured data should look like that of Figure 4, and the
performance should be similar to that of Table 1.
NOTE: After performing the capture, ensure that the amplitude of the analog input signal is –1 dBFS
