The Brandywine Communications JXI2 PCI-SyncClock32 is a high-precision timing module designed for integration into PCI bus systems. This module offers robust synchronization capabilities, ensuring accurate timekeeping and clock signal distribution for demanding industrial, scientific, and telecommunications applications. The PCI-SyncClock32 leverages an on-board microprocessor to automatically synchronize its internal clock to various reference signals, including IRIG A, B, NASA 36, 1PPS, and optionally GPS or Have Quick. This advanced synchronization mechanism, coupled with propagation delay correction and zero-latency time reads, enhances system reliability and performance by minimizing timing errors. The module also features user-programmable clock rates, external event time tagging, and a Match Time output for precise control of external processes.
