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

Description

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 understandingExample Verilog code is an easy starting point for FPGA to high-speed data converter applicationsDesign is easily expanded to other TI high-speed data convertersThe ADC and DAC portions are split in case only one is requiredInterface timing constraints are discussed in detail for the DAC and ADCFirmware was tested using readily available TI EVMs
Applications
  • Repeater
  • Flight control system
  • Data acquisition (DAQ)
  • Electronic warfare
  • Active antenna system mMIMO (AAS)
  • Macro remote radio unit (RRU)
Product Categories
  • Data converters
