TIDA-00419
概覽
This reference design is a demonstration of a SONAR receive-path sub-system using the integrated analog front end (AFE) AFE5809. AFE5809 features eight 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 AFE5809EVM with TSW1400EVM FPGA capture card and their respective software GUIs in order simulate a receive chain solution capable of high-performance measurement.
特點
- Capable of measuring SONAR signals from 30 kHz to 32.5 MHz
- Digital demodulator for envelope detection and beamforming
- Variable-sample frequency 10 MSPS to 65 MSPS with external clock capability
- Variable-gain settings with a -4-dB to 54-dB range
- Variable-input impedance settings
- Tested and provides reference materials including schematics and bill of material (BOM)
