Overview

The DAC38RF89 evaluation module (EVM) is the circuit board for evaluating DAC38RF89 digital-to-analog converters (DACs). The DAC38RFEVM can be used to evaluate the performance of the DAC up to 9-GSPS sampling rate and is designed to work with the TSW14J56EVM (Rev B and up). The available FMC connector also makes it possible to interface the DAC to an FPGA development board from third-party vendors. Also available is an easy-to-use software interface to control the DAC and onboard LMK04828 clock chip via SPI.

Features
  • Allows evaluation of DAC38RF89 up to 9-GSPS sampling rate
  • Supports up to 12.5-Gbps SerDes signaling rate across FMC
  • Two on-chip PLLs with superior phase noise to simplify system clock generation; also supports external clock mode
  • AC-coupled output with integrated impedance transformer (DAC38RF89) for balanced-to-unbalanced conversion
  • Easy-to-use software interface and data pattern-generation tools
