BUS-61559 SERIES

MIL-STD-1553B NOTICE 2

ADVANCED INTEGRATED MUX HYBRIDS

WITH ENHANCED RT FEATURES (AIM-HY’er)

DESCRIPTION

DDC’s BUS-61559 series of Advanced

Integrated Mux Hybrids with enhanced

RT Features (AIM-HY’er) comprise a

complete interface between a micro-

processor and a MIL-STD-1553B

Notice 2 bus, implementing Bus

Controller (BC), Remote Terminal (RX,

and Monitor Terminal (MT) modes.

Packaged in a single 78-pin DIP or

82-pin flat package the BUS-61559

series contains dual low-power trans-

ceivers and encoder/decoders, com-

plete BC/RT/MT protocol logic, memory

management and interrupt logic, 8K x 16

of shared static RAM, and a direct,

buffered interface to a host processor bus.

buffers to provide a direct interface to

a host processor bus. Alternatively,

the buffers may be operated in a fully

transparent mode in order to interface

to up to 64K words of external shared

RAM and/or connect directly to a com-

ponent set supporting the 20 MHz

STANAG-3910 bus.

The memory management scheme

for RT mode prevails an option for

separation of broadcast data, in com-

pliance with 1553B Notice 2. A circu-

lar buffer option for RT message data

blocks offloads the host processor for

bulk data transfer applications.
