DAC3282
This is the user’s guide for the DAC328x EVM. The EVM includes the TRF372017 quadrature modulator
to facilitate measuring the output signals at a desired RF frequency. The TRF372017 includes an
integrated RF synthesizer used for the LO. The EVM also includes the CDCE62005 clocking source which
provides the clocks required for the DAC, the pattern generator, and the synthesizer reference of the RF
modulator. This EVM is ideally suited for mating with the TSW3100 pattern generation card for evaluating
WCDMA, LTE, or other high-performance modulation schemes.
