CAES UT69151-RTE

Deriving its name from Serial, µ-coded, Monolithic, Multi-mode, Intelligent, Terminal, the monolithic SµMMIT™ family provides the system designer with an intelligent solution to MIL-STD-1553 multiplexed serial data bus design problems.

Each SµMMIT device is a single-chip that implements all three of the defined MIL-STD-1553 functions - Remote Terminal, Bus Controller, and Monitor. Operating either autonomously or with a tightly coupled host, the SµMMIT devices solve a wide range of MIL-STD-1553 interface problems.

The UT69151 SµMMIT™ RTE (Remote Terminal) is an interface device linking a MIL-STD-1553 serial data bus to a host microprocessor and/or subsystem. The device’s MIL-STD-1553 interface includes encoding/decoding logic, error detection, command recognition, DMA interface, control/ configuration registers, clock, and reset logic.

SPO-2015-PA-0001
The objective of this product advisory is to inform MIL-STD-1553 circuit designers of lessons learned during a residual voltage investigation and to offer some transformer selection recommendations to minimize residual voltage.

SPO-2015-PA-0001A
This amendment adds BTTC as an approved transformer supplier for optimal compatibility with the Cobham 1553 Transceiver. The results of the BTTC compatability study are included. A final recommendation for leakage inductance screening limits is defined.
