DESCRIPTION
The BUS-65153 is a complete, dual
redundant MIL-STD-1553B Remote
Terminal. Packaged in a 1.9" x 1.0" x
0.2", 70-pin ceramic package, the
BUS-65153 provides the transmitter
voltage level required by MIL-STD-
1760. Also in support of MIL-STD-
1760, the RT address inputs are
latchable.
The BUS-65153 contains two low power
transceivers and a DDC custom designed
chip.
This
chip
includes
dual
encoder/decoder, RT protocol logic, tri-
state data buffers, and DMA transfer con-
trol logic. The BUS-65153 supports all 13
dual redundant mode codes, any combi-
nation of which may be illegalized by an
external PROM, PLD, or RAM device.
Parallel data transfers are accomplished
via a DMA type interface. Both 8-bit and
16-bit transfers are supported.
The BUS-65153 can be easily inter-
faced to most CPU's. In addition, the
BUS-65153 can interface directly to
minimum
complexity
subsystems
such as switches, D/A converters,
etc.
The address bus and transfer control sig-
nals may be configured for either two-state
or three-state operation. Use of the three-
state address mode reduces the number
of external components required for a
DMA processor interface.
The input clock frequency is user
selectable for either 12 or 16 MHz. In the
12 MHz mode, the decoder operates at 24
MHz, providing superior word error rate
and zero crossing distortion tolerance. The
Busy, Service Request, and Subsystem
Flag RT Status Word bits are provided as
discrete pins, allowing for easy access by
the subsystem.
Various message timing and error
flag indicators are provided to facili-
tate the subsystem interface.
