Terminal Board

The LVME1553-2 Dual 1553 Terminal Board provides full, intelligent interfacing between two independent dual redundant MIL-STD-1553B Data Busses and the VMEbus.
A special Direct Interface, allows the 1553 terminals to be connected directly to a CPU bus located on another VMEbus board, therefore bypassing the VMEbus latency.
Software controls the operation of each independent channel of the LVME1553-2 as either a MIL-STD-1553 Bus Controller (BC), Remote Terminal (RT) or Bus Monitor Terminal (MT).
At the core of the unit are two ILC DDC Corp dual-redundant BUS-61553 Advanced Integrated Mux Hybrids, operating at 16MHz clock rate . The LVME1553-2 board may be configured with one or two BUS-61553 components, providing and option to interface with up to two independent 1553 buses using a single double Eurocard.
Each 1553 channel contains 8Kx16 or 64Kx16 of on-board protocol SRAM. The shared RAM is fully double buffered, preventing partially updated data from being read by the VMEbusCPU host or transmitted to the 1553 data bus.
