DESCRIPTION
The BU-61703/5 Simple System RT (SSRT) MIL-STD-1553 terminals
provide a complete interface between a simple system and a MIL-
STD-1553 bus. These terminals integrate dual transceiver, protocol
logic, and a FIFO memory for received messages in a 1.0 inch square
ceramic package. The SSRT provides multi-protocol support of MIL-
STD-1553A/B, MIL-STD-1760, McAir, and STANAG-3838.
The SSRT's transceivers are completely monolithic, require only a
+5V supply, and consume low power. There are versions of the sim-
ple system RT available with transceivers trimmed for MIL-STD-1760
compliance, or compatible to McAir standards. As a means of further
reducing power consumption, the SSRT is available in versions with
its logic powered by +3.3V, or +5V. The SSRT can operate with a
choice of clock frequencies of 10, 12, 16, or 20 MHz.
The SSRT incorporates a built-in self-test (BIT). This BIT, which is
processed following power turn-on or after receipt of an Initiate self-
test mode command, provides a comprehensive test of the SSRT's
encoders, decoders, protocol, transmitter watchdog timer, and proto-
col. The SSRT also includes an auto-configuration feature.
The SSRT is ideal for stores and other simple systems that do not
require a microprocessor. To streamline the interface to simple sys-
tems, the SSRT includes an internal 32-word FIFO for received data
words. This serves to ensure that only complete, consistent blocks of
validated data words are transferred to a system.
