DAC FPGA design (compatible to SU741):
- only the differences:
- D0..D3 are SPI signals (inputs) when FCLR=1, so the LogicBox main board can directly access the two DACs.
- HISTO and CRE are not used, histogramming mode is not available
- Addr<2> is SYNC, a clock used for the time measurement, typically 10 or 100 MHz.
- compared to SU741 the differences are
- the position of the SPI signals (when driven from the SU-Connector(LogicBox))
- the memory size (8 M x 16) is twice the memory on SU741 (4 M x 16)
- two DACs (SU730) instead of 8 (SU741)
- no initialisation of the two DACs (necessary for SU741)
