The all CMOS Multi-Chip Module (MCM) technology provides low standby power dissipation together with a pact footprint in PGA or surface mount (quad-flatpack) packages. This RTU provides a standalone interface between the MIL-STD-1760 or MIL-STD-1553 Bus and the subsystem. The module is available with (RTM1760) or without (RTS1760) an internal 4k x 16 RAM. .. .cmac. GENERAL DESCRIPTION The RTS/RTM1760 is a plete dual redundant MIL-STD1760 or MIL-STD-1553B Remote Terminal in a single small outline package. It is also capable of meeting the Mc Air response time requirements and the optional handling of modecode descriptor 31 as a normal subaddress. The mode of operation is selectable using two external pins. The RTS/ RTM1760 contains two low-power monolithic transceivers capable of providing the output voltage required for MILSTD-1760 (20V to 27V) together with a custom protocol chip and an optional 4K x 16 RAM for message storage. The custom transceiver chips are implemented in CMOS technology providing very low power consumption .. figures when not transmitting. The receiver sections of the transceivers fully meet the requirements of MIL-STD-1553B in terms of threshold, mon mode rejection and bit error rate when used in conjunction with the custom protocol chip. The custom protocol chip contains dual redundant encoder/ decoders, RT protocol logic, 32 word message buffers, DMA controller, arbitration logic and control registers....
