The different SCD boards differ primarily in signal level. Configurable through Field Programmable Gate Array (FPGA) files.
Standard FPGAs shipped with SCD products include:
Custom FPGAs are also available. |

The SSD4 is actually a SCD-20 with an SSD4 FPGA
(included in the SCD-20 package) downloaded. The hardware
is identical to the SCD-20; separate product listings and data
sheets are maintained for historical purposes only. |
