LatticeECP3 I/O Protocol Evaluation Board

The LatticeECP3 IO Protocol Evaluation Board provides a convenient platform to evaluate, test and debug user designs and IP cores targeted for the LatticeECP3 FPGA. The LatticeECP3 I/Os are connected to a rich variety of both generic and application-specific interfaces.

Some common uses for the LatticeECP3 IO Protocol Evaluation board include:

  • Applications requiring large DDR3 memory width and depth
  • High-speed parallel ADC/DAC Interface
  • SERDES data transfer with external devices
  • 1000base-T PHY/RJ45 networking
  • A single-board computer system
  • A platform for evaluating the Input/Output (I/O) characteristics of the FPGA
  • A platform for evaluation and development with Lattice IP cores

ADC-DAC Interface Card

The ADC-DAC interface card connects to the HMZD connector on the IO protocol board, and has two connectors that match ADC and DAC boards from TI.
