The Moog Broad Reach Payload Interface Board (PIB) provides configurable Customer and Mission specific data interfaces and mass storage. A typical board delivers 1Gbyte of EDAC SDRAM for mass storage, 4 configurable high-rate synchronous/ asynchronous payload receive interfaces, 4 configurable real-time asynchronous receive interfaces, 4 configurable asynchronous command interfaces, 32 Bi-level inputs, 32 Bi-level outputs, 16 open-collector outputs, and 32 differential analog channel inputs. Radiation hardened and fault tolerant components make the PIB a robust I/O connection. The board utilizes the radiation hardened Actel RTAX2000 FPGA for its 32-bit 33MHz PCI target, SDRAM controller, and all customer-defined payload interface functions.
