3DR Thunder II – 8-channel, 16-bit, 11.5 GSPS Digital-to-Analog Converter
The 3DR-A10-DAC-11.5 GSPS, known as Thunder II, is an eight channel, 16 bit, 11.5 GSPS digital-to-analog converter board used to convert digital signals into analog waveforms. The on-board Intel Arria 10 FPGA (10AX115U2F45I2SG) can digitally generate waveforms or playback pre-stored samples. As with all 3DR computing modules, Thunder II supports three-dimensional connectivity, allowing the user to stack and/or tile modules to address a wide variety of processing, I/O, size, weight, and power requirements. Thunder II also offers an additional external interface via SMA for tailored clocking and control signal flexibility. The 3DR computing standard microcontroller architecture is interfaced through the I2C bus to provide FPGA temperature, voltage, and current monitoring for automatic shut-down during critical overheat and/or voltage conditions.
