This user guide will discuss how to use the evaluation boards and software to configure and collect data from the EVAL-ADA4355EBZ and EVAL-ADA4356EBZ boards.

Overview

The ADA4355 and ADA4356 are integrated receive uModules that combine a programmable gain transimpedance amplifier (PGTIA), a fully differential amplifier (FDA), a low-pass filter, and a high-speed ADC in a single package. These devices are designed for optical time-domain reflectometry (OTDR), LiDAR, and fiber sensing applications.

Two evaluation platforms are available:

  • EVAL-ADA4355EBZ — evaluates the ADA4355 using a Xilinx KC705 FPGA platform with a MATLAB-based GUI.

  • EVAL-ADA4356EBZ — evaluates the ADA4356 using a ZedBoard FPGA platform with Linux, HDL, PyADI-IIO, and IIO Oscilloscope.

Note

Although the GitHub URLs and filenames refer to ADA4355, the software is for ADA4356 as well.

Recommendations

People who follow the flow that is outlined have a much better experience with things. However, like many things, documentation is never as complete as it should be. If you have any questions, feel free to ask on our EngineerZone forums, but before that, please make sure you read our documentation thoroughly.

Warning

All the products described on this page include ESD (electrostatic discharge) sensitive devices. Electrostatic charges as high as 4000V readily accumulate on the human body or test equipment and can discharge without detection. Although the boards feature ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. This includes removing static charge on external equipment, cables, or antennas before connecting to the device.
