Over-engineered SDR development board

icyradio

A Software Defined Radio development board.

Initial project codename Icyradio originated from the device family name of the FPGA used in the first version (ICE40). Coincidently, the device family name of the FPGA used in this version (Artix) also resembles a very cold region, the Arctic, hence, the project codename still holds some of its sense 😊.

Main components

• XC7A100T-2FGG484 - FPGA
• Raspberry Pi CM4 - Raspberry Pi Compute Module 4
• MT41K256M16TW-125 - DDR3 RAM
• AD9361 - Agile RF Transceiver
• SI5351C - System clock synthesizer
• 8V97003 - Frequency Synthesizer for external mixer support
• ADAU1372 - Audio CODEC
• UPD301C - USB Power Delivery controller
• LT7182S - Main Buck regulator

Functional block diagram

v2

Note: From v2 onwards, the only components in this repository are hardware related, no specific application software, like in v1 branches. Applications that use this hardware are kept in a separate repository (TODO: Add link) The goal of this project is to develop a flexible and feature rich SDR platform for tinkering. It will include, among other features, a mmWave synthesizer controlled by software to allow external mixers to be attached to the SDR and extend its frequency range (i.e. for 5G applications), and also allow interfacing to a Raspberry Pi Compute Module 4 for standalone operation.

Dependencies

• vivado - FPGA toolchain
• arm-none-eabi-gcc - PD Controller MCU toolchain
• Device CMSIS - CMSIS headers defining the MCU memories, peripherals, etc...
• Core CMSIS - CMSIS headers defining the ARM Cores
• armmem - ELF file analyzer (required for the MCU Makefiles to work)
• SoapySDR - Vendor and platform neutral SDR support library

Software build instructions
