This document is intended to serve as a basic user's guide for the DAC31x1 EVM. The EVM provides a
basic platform to evaluate the DAC31x1, which is a 500 MSPS, high speed digital-to-analog converter.
The DAC3171 is a single-channel DAC with 14-bit LVDS input. The DAC3171 is pin compatible with the
single-channel, 12- and 10-bit, 500 MSPS digital-to-analog converter, DAC3161 and DAC3151. The
DAC3174EVM GUI is used for the DAC31x1EVM.
The EVM includes the CDCE62005 clocking source which provides the clocks required for the DAC and
the pattern generator. This EVM is ideally suited for mating with the TSW1400 pattern generation card for
evaluating WCDMA, LTE, or other high performance modulation schemes.
