Block diagram
Notes:
- The ADC is the ADS54J54 (Texas Instruments)
- All clocks are generated by the Si5394 (Silicon Labs). The device has a working configuration during start-up, but can also be programmed during operation.
- Optional synchronization to external clock source
- DC/DC converters can be synchronized to a frequency generated by the FPGA
