SIS3820 I/O Register Firmware FlavorsThe SIS3820 PCB -which is the base for the SIS3820 multi purpose scaler- is used to implement Input/Output modules also. The base card (i.e. without VME64x transition board features 32 I/O channels and 8 control I/O channels. The logic levels can be NIM, TTL, ECL and LVDS. On the connector side you can select between LEMO 00 and pin headers for flat cables. Mixed level and connector versions are available also. The firmware can be upgrade in field over VME or a JTAG connection.
Feel free to inquire about custom firmware implementations.
