The SIS3802 is the prescaler firmware implementation on the base of the SIS38xx/3600 base board. The module is designed to replace NIM switch prescalers for trigger prescaling and similar particle physics applications. Up to four prescaled outputs can be implemented per channel via a signal routing and driver piggy pack. The transition time of the unit is prescale factor independent, its below 11 ns. The prescaler is a single width 6U VME card, no non standard voltages are required. The unit comes with a 20 pin header connector for the input section and two 34 pin headers for the outputs (ECL and flat cable TTL version) or via 8 LEMO connectors for the inputs and 32 LEMOs for the outputs (NIM and LEMO TTL version) .
