Abstract

Development of the VLF LEAF Module continues despite the global electronic component shortage. Since the Tangerine SDR cannot be built currently due to long lead times of the Intel Max 10 FPGA, the Max 10 FPGA development board was repurposed for Tangerine SDR Development. An adapter board was designed that allows the Clock Module and RF Module to be interfaced to the Max 10 development board for Verilog development of the Tangerine SDR. Since the LEAF module is too large for the adapter board, the adapter board will include a connector to interface the TI TLV320ADC6140 Evaluation (DUT) board. The DUT board includes the TLV320ADC6140 and all supporting circuitry to spearhead Verilog development of the VLF LEAF module. The FPGA will add GPS timestamping to the recorded samples and reformat the stream to be compatible with vlfrx-tools, an open source signal processing tool set with many applications, including VLF/ULF signal processing.
