Description

The TIDA-00419 TI Design is a demonstration of a SONAR receive path sub-system using the integrated analog front end (AFE) AFE5809. The AFE5809 features 8 channels of analog signal conditioning  (LNA+VCAT+PGA) and Digital Processing (ADC+Digital Demodulator) that brings a high level of system receive path integration and enables high-performance echo-location imaging for high-end SONAR systems. This reference design demonstrates this SONAR sub-system with a schematic modified from the AFE5809EVM. The test data included is taken by combining the full AFE5809EVM with the TSW1400EVM FPGA Capture Card and their respective Software GUIs in order simulate a complete receive chain solution capable of high-performance measurement.

Features
  • Capable of measuring SONAR signals from 30kHz-32.5MHz
  • Digital Demodulator for envelope detection and beamforming
  • Variable Sample frequency 10-65MSPS with external clock capability
  • Variable Gain settings with a -4dB to 54dB range
  • Variable input impedance settings
  • This design is tested and provides design reference materials including Schematics, and BOM.
