EVM Use With the TSW1100

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

3 EVM Use With the TSW1100
The ADS5231/32/37 EVM allows for connection to the TSW1100, allowing easy capture and analysis of
the ADC digital output data. See the TSW1100 Data Capture Board Quick Start Guide (SLAU155) and
TSW1100 User's Guide (SLAU164) for more information.
