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
