General Description
The CT2565 is a dual redundant MIL-STD-1553 Bus Controller (BC), Remote Terminal (RT), and
Bus Monitor, (BM) Bus packaged in a 1.9" x 2.1" hermetic hybrid. It provides all the functions
required to interface a MIL-STD-1553 dual redundant serial data bus transceiver, (Aeroflex's
ACT4487 for example) and a subsystem parallel three-state data bus. Utilizing a custom monolithic
IC, the CT2565 provides selectable operation as a Bus Controller, Remote Terminal or a Bus
Monitor (BM).
The CT2565 is compatible with most µprocessors. It provides a 16 bit three-state parallel data bus
and uses direct memory access (DMA type) handshaking for subsystem transfers. All message
transfer timing as well as DMA and control lines are provided internally. Subsystem overhead
associated with message transfers is therefore minimized. Interface control lines are common for
both BC and RT operation.
The CT2565 features the capability for implementing all dual redundant MIL-STD-1553 mode
codes. In addition, any mode code may (optional) be illegalized through the use of an external
(200ns access time) PROM. Complete error detection capability is provided, for both BC and RTU
operation. Error detection includes: response time-out, inter message gaps, sync, parity,
Manchester, word count and bit count. The CT2565 complies with all the requirements of
MIL-STD-1553.
The hybrid is screened in accordance with the requirements of MIL-STD-883 and operates over the
full military temperature range of -55°C to +125°C.
