DESCRIPTION
DDC's BU-61590 BC/RT/MT
Universal Advanced Communication
Engine (ACE) terminal comprises a
complete integrated interface between
a host processor and a MIL-STD-
1553, STANAG 3838, or McAir bus.
The BU-61590 integrates a dual uni-
versal McAir transceiver, protocol,
memory management and processor
interface logic, and 4K words of inter-
nal buffered RAM in either a 78-pin
DIP or flat pack package.
This dual universal tr ansceiv er pro vides
a sinusoidal waveform for full compli-
ance with 1553A, 1553B, and McAir
A3818, A5232, and A5690 standards.
To minimize board space and "glue"
logic, the Universal ACE terminals
provide the ultimate flexibility in inter-
facing to a host processor and inter-
nal/exter nal RAM.
The BU-61590 provides complete
multiprotocol support of MIL-STD-
1553A, 1553B Notice 2, McAir A3818,
A5232, and A5690, General
Dynamics 16PP303, Grumman
SPG151A, and STANA G 3838 (includ-
ing EFAbus).The advanced functional
architecture of the ACE ter minals pro-
vides software compatibility to DDC's
previous AIM series hybrids. In addi-
tion, the ACE Terminals incor porate a
multiplicity of architectural enhance-
ments allowing fle xib le operation while
off-loading the host processor, ensur-
ing data consistency, and supporting
bulk data transfers.
The BU-61590 may be operated at
either 12 or 16 MHz.Options allow f or
a hardwired or programmable RT
address.
The BU-61590 operates over the full
military temperature range of -55 to
+125°C. Available screened to MIL-
PRF-38534, the terminals are ideal
for demanding military and industrial
processor-to-1553 applications.

Notes:
1. Specifications include both transmitter and receiver (tied together internally).
Measurement of impedance is directly between pins TX/RX A(B) and TX/RX
A(B) of the BU-61590X5 hybrid. Assuming the connection of all power and
ground inputs to the hybrid. The specifications are applicable for both unpow-
ered and powered conditions.The specifications assume a 2 volt rms balanced
differential, sinusoidal input.The applicable frequency range is 75 kHz to 1
MHz. Minimum resistance and maximum capacitance parameters are guaran-
teed, but not tested, over the operating range.
2.Typical value for minimum intermessage gap time. Under software conlrol, may
be lengthened to (65,535 µs minus message time), in increments of 1 µs.
3. Software programmable (4 options). Includes RT-to-RT Timeout (Mid-Parity of
Transmit Command to Mid-Sync of Transmitting RT Status).
