DESCRIPTION

The BU-64703 Simple System RT Mark3 (SSRT Mark3) MIL-

STD-1553 terminal provides a complete interface between a simple

system and a MIL-STD-1553 bus. The SSRT Mark3 can be powered

entirely by 3.3 volts, thus eliminating the need for a 5V power supply.

This terminal integrates dual transceiver, protocol logic, and a FIFO

memory for received messages in an extremely small, 0.88 inch

square 0.130” max height ceramic package. The gull wing package

with a “toe-to-toe” maximum dimension of 1.110 inches enables its

use in applications where PC board space is at a premium. The

SSRT Mark3 provides multi-protocol support of MIL-STD-1553A/B,

MIL-STD-1760, McAir, and STANAG-3838.

The SSRT Mark3's transceivers are completely monolithic, require

only a +3.3V supply (+5.0V available), and consume low power. The

internal architecture is identical to that of the original BU-61703/61705

Simple System RT (SSRT). There are versions of the Simple System

RT Mark3 available with transceivers trimmed for MIL-STD-1760

compliance, or compatible to McAir standards. The SSRT Mark3 can

operate with a choice of clock frequencies at 10, 12, 16, or 20 MHz.

The SSRT Mark3 incorporates a Built-In-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

Mark3's encoders, decoders, protocol, transmitter watchdog timer,

and protocol section. The SSRT Mark3 also includes an auto-config-

uration feature.

The SSRT Mark3 is ideal for stores and other simple systems that do

not require a microprocessor. To streamline the interface to simple

systems, the SSRT Mark3 includes an internal 32-word FIFO for

received data words. This serves to ensure that only complete, con-

sistent blocks of validated data words are transferred to a system.
