This presentation will cover the current status of FPGA firmware and module testing
on the Tangerine SDR system. The system is currently using the MAX10 Development
kit, the Tangerine receiver module and clock module, and an adaptor between the
components and the Development board. The development system used Intel Quartus
version 20.1 on Linux.

The PSWS clock module provides a high accuracy frequency and time source for the TangerineSDR.\  It will also be available in a standalone version called the "SynthDO" for other time and frequency applications.\  The clock module has gone through a major revision in design philosophy and the current version combines significantly lower component cost with great flexibility in the output configuration.\  This presentation will describe the new architecture and point out some of its pros and cons.

First conceived in 2018 at the ARRL/TAPR Alubuquerque Digital Communications Conference, the modular TangerineSDR has gone through many architecture changes and upgrades. The first use case will be the Personal Space Weather Station (PSWS). The boardset consists of three custom boards: the Data Engine (DE), the Clock Module (CKM) and the RF Module (RFM). Now that we are nearing prototype hardware, here is an overview of the final architecture and the status of the prototype build.
