DAC31x2EVM
This document is a user's guide for the DAC31x2EVM, an evaluation fixture for the DAC3152 and
DAC3162 (DAC31x2) series of dual-channel, 10-/12-bit, 500-MSPS digital-to-analog converters (DACs).
The DAC31x2EVM includes the TRF3703-33 quadrature modulator to facilitate measuring the output
signals at a desired RF frequency. The EVM also includes the CDCP1803 clock buffer that distributes the
clocks to the DAC, as well as a pattern generator. This EVM is ideally suited for mating with the TSW3100
pattern generation card for evaluating QAM, WCDMA, LTE, or other high-performance modulation
schemes. For more information about the DAC31x2 family, see the product data sheet (available for
download at www.ti.com).
Throughout this document, the acronym EVM and the phrases evaluation module and evaluation fixture
are synonymous with the DAC31x2EVM.
