Important

This guide focuses on LTC2378-20 with the ZedBoard for Linux (the primary and most supported path) and the DC2135A with the MAX32666FTHR for no-OS. The setup applies to all other supported devices as they share the same FMC connector and pin-compatible interface.

Hardware guide

Hardware configuration

The LTC2378-20 FMC evaluation board connects to the ZedBoard via the FMC connector.

Power supply

The FMC connector on the ZedBoard supplies all voltages required by the evaluation board. No separate external supply is needed for the FMC board itself. The ZedBoard is powered by its own 12V DC supply included in the ZedBoard kit.

The VADJ level on the ZedBoard must be set to 2.5V to match the I/O voltage requirements of the LTC2378-20.

Software guide

The LTC2378-20 reference design runs the ADI Kuiper Linux distribution on the ZedBoard. The ADC is exposed through the Linux IIO (Industrial I/O) subsystem, which provides a standardized interface for data acquisition.

Once the board has booted, the following IIO-based tools can be used to interact with and capture data from the device:
