TSW2170EVM Evaluation Module (EVM)
This user’s guide describes the operation of the TSW2170 signal generator evaluation module (EVM). The
EVM is a low-cost tool used to verify the functionality of various TI analog-to-digital converters (ADCs).
This document has setup instructions, block diagrams and screen captures from actual experiments using
the TSW2170EVM. The TSW2170EVM product folder on the TI web site contains the EVM schematic, bill
of materials, and layout files.

1 Introduction
The TI TSW2170EVM (EVM) helps designers evaluate the functionality of their ADC devices. This product
eliminates the expense of using a signal generator to create an input signal.
The board is powered off a bench power supply or the 5-V output which is found on the TSW2200EVM.
An external clock generator is required to provide a sampling clock for the ADC board to capture correctly.
For the captures conducted in this document, a 245.76-MHz clocking signal from the TSW4806EVM was
used.
