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.
