IP-1553-2 Dynamic Engineering MIL-STD-1553 Interface IndustryPack Module

The Dynamic Engineering IP-1553 Series MIL-STD-1553 Interface IndustryPack Modules is part of the IndustryPack "IP" Module family of modular I/O components by Dynamic Engineering. IP-1553 provides two independent 1553 controllers each with redundancy. The Holt Integrated Circuits 62203 interf62203 provides the protocol processing, integrated transceivers and integrated transformers. Multiple taps provide the Direct or Transformer coupled capability. IP-1553 can be selectively built with one or two 1553 controllers.

The 62203 supports programmable BC / MT / RT operation. To support the 62203, IP1553 uses an FPGA to provide the IP decoding to 62203, clocking to the 1553 controller, interrupt processing, and other support functions.

The internal decoding performed within the FPGA is synchronized to the 1553 clock. A frequency doubler is used to allow tighter timing control over the asynchronous interface the 62203 employs. With the tighter timing fewer wait-states are required for an access from the IP bus. The internal rate is 40 MHz and the 62203 is provided a 20 MHz. reference.

IP-1553 is 8 and 32 MHz compatible. 32 MHz is recommended. The 62203 provides a done signal; the local state-machine utilize to determine the end of each transfer. Reads and Writes are performed with optimized interaction to the 62203. The 62203 has registers and memory.

The 64K memory within each 62203 device exceeds the size of the IP IO space. The Memory space is used to decode the 62203 addresses. Address bit 18 is used to select the 62203 device and Address bit 17 to select between Register and Memory within each 62203. The IO space is used to decode the control registers within the FPGA.

Each channel has a control register within the FPGA to set the channel specific options. Each channel has a portion of the IP Memory space allocated to allow direct offsets based on the 62203 addresses to be utilized.

All FPGA configuration registers support read and write operations for maximum software convenience. 62203 has register dependent R/W capability.

IP-1553 conforms to the IndustryPack standard. This guarantees compatibility with compliant carrier boards. Because the IP-1553 may be mounted on different form factors, while maintaining plug and software compatibility, system prototyping may be done on one Carrier board, with final system implementation on a different one. For example the PCIe3IP - PCI carrier for IP Modules can be used for development in a conventional PC. Later the hardware and software can be ported to the target.
