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)

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)
