User's Guide SBAU111A – May 2006 – Revised June 2007 ADS5231/32 EVM This preliminary user’s guide gives a general overview of the ADS5231/32 evaluation module (EVM), and provides a general description of the features and functions to be considered while using this module. Overview Purpose The ADS5231/32 EVM provides a platform for evaluating the ADS5231/32 dual, 12-bit, analog-to-digital...
www.ti.com Circuit Description 3. Switch power supplies on 4. Use a function generator with 50-Ω output to input a 45-MHz, 1.5-V offset, 3-V square-wave signal into J3. The frequency of the clock must be within the specification for the device speed grade. Caution: the ADS5231/32 does not work with a sinusoidal clock source.

2.2.5 Outputs The data outputs from the ADC are buffered using two Texas Instruments SN74AVC16244s. Output data headers J8 and J21 are standard 40-pin headers on a 100-mil grid, and allow easy connection to a logic analyzer or TSW1100. The connector pinout is listed in Table 2.
Use either a wall-mount transformer that has an output rating of 12 VDC and 500 mA or a lab power supply that can supply 12 VDC. Connect the output to J8 and the return to J9. Texas Instruments recommends setting a current limit of 500 mA. Power on the TSW1100.
Launching the TSW1100 Software With the TSW1100 recognized by the hardware device manager, the software package can be run. To run the program, click on Start → Program Files → Texas Instruments → TI ADC Capture Card. Using the TSW1100 Software Using the TI chip selector, select the ADS5231/32.
