FPGA Firmware Example of How To Interface Altera FPGAs to High-Speed LVDS-Interface Data Converters

TIDA-00069

Design files

Overview

This reference design and the associated example Verilog code can be used as a starting point for interfacing Altera FPGAs to Texas Instruments' high-speed LVDS-interface analog-to-digital converters (ADC) and digital-to-analog converters (DAC). The firmware implementation is explained and the required timing constraints are discussed.

Features
  • This design is Firmware only and is discussed in detail to aid understanding
  • Example Verilog code is an easy starting point for FPGA to high-speed data converter applications
  • Design is easily expanded to other TI high-speed data converters
  • The ADC and DAC portions are split in case only one is required
  • Interface timing constraints are discussed in detail for the DAC and ADC
  • Firmware was tested using readily available TI EVMs
