Standard Products UT63M143 MIL-STD-1553A/B Bus +3.3V Transceiver Datasheet March 18, 2011 www.aeroflex.com/HiRel FEATURES INTRODUCTION 3.3-volt only operation The monolithic UT63M143 Transceivers are complete transmitter and receiver pairs for +3-volt MIL-STD-1553A and 1553B applications. Encoder and decoder interfaces are idle low. Dual-cavity monolithic silicon technology Fit and functionally compatible to industry standard transceiver The receiver section of the UT63M143 series accepts biphasemodulated Manchester II bipolar data from a MIL-STD-1553 data bus and produces TTL-level signal data at its RXOUT and RXOUT outputs. An external RXEN input enables the receiver outputs or disables them low. Idle low transmitter inputs and receiver outputs Operating temperature range: -55C to +125C Operational environment: - Total-dose tolerance: 300 krads and 1Mrad(Si) - SEL Immune to a LET of 111 MeV-cm2/mg The transmitter section accepts biphase TTL-level signal data at its TXIN and TXIN and produces MIL-STD-1553 data signals. The transmitter’s output voltage is typically 7.1 VPP,LL. Activating the TXIHB input or setting both data inputs to the same logic level disables the transmitter outputs. Packaging options: - 24-lead flatpack, dual-channel 50-mil center - 36-pin DIP, dual-channel 100-mil center Standard Microcircuit Drawing (SMD): 5962-07242 The UT63M143 series offers complete transmitter and receiver pairs packaged in a dual-channel 36-pin DIP or 24-lead flatpack configurations designed for use in any MIL-STD-1553 application. - QML Q and QML V compliant part RXEN RXOUT RXIN RXIN FILTER and LIMITER FILTER TO DECODER RXOUT THRESHOLD REFERENCE TXOUT TXIN DRIVERS COMPARE FROM ENCODER TXOUT TXIN TXIHB Figure 1.

The transmitter current drivers are coupled to a MIL-STD-1553 data bus via a transformer driven from the TXOUT and TXOUT terminals. The transmitter output terminals’ non-transmitting state is enabled by asserting TXIHB (logic “1”), or by placing both TXIN and TXIN at the same logic level. Reference Table 1, Transmit Operating Mode, for a list of the functions for the output data in reference to the state of TXIHB. Figure 3 shows typical transmitter waveforms. BOTH HIGH OR BOTH LOW TXIN TXIHB LINE-TO-LINE DIFFERENTIAL OUTPUT TXOUT, TXOUT 90% 10% RECEIVER The receiver section accepts biphase differential data from a MIL-STD-1553 data bus at its RXIN and RXIN inputs. The receiver converts input data to TTL-level, biphase Manchester II format and is available for decoding at the RXOUT and RXOUT terminals. The outputs RXOUT and RXOUT represent positive and negative excursions (respectively) of the inputs RXIN and RXIN. Figure 4 shows typical receiver output waveforms. TXIN TXIN tTXDD Table 1.

Typical Receiver Waveforms 5 DATA BUS INTERFACE 1 The designer can connect the UT63M143 to the data bus via a short-stub (direct-coupling) connection or a long-stub (transformercoupling) connection. Use a short-stub connection when the distance from the isolation transformer to the data bus does not exceed a one-foot maximum. Use a long-stub connection when the distance from the isolation transformer exceeds the one-foot maximum and is less than twenty feet. Figure 5 shows various examples of bus coupling configurations. The UT63M143 series transceivers are designed to function with MIL-STD-1553A and 1553B compatible transformers. Note: 1. The 24-lead flatpack internally connects TXOUT to RXIN and TXOUT to RXIN for each channel.

To insure proper heat transfer between the package and the heat removal rail, use a thermally-conductive material between the package and the heat removal rail. Some recommends using a material like AI Technology ME7158, ME7159, or Eccobond 45 with Eccobond 15LV catalyst to insure heat transfer between the package and heat removal rail. 8 ABSOLUTE MAXIMUM RATINGS 1 PARAMETER LIMITS UNIT -0.3 to +7.0 V 8 VPP -0.3 to VDD +0.3 V Maximum Package Power dissipation @ Tc=+125oC 2 7.1 W Thermal impedance junction to case2 7.0 C/W +175 C -65 to +150 C VDD Input voltage range (receiver) Logic input voltage range Maximum junction temperature Storage temperature Receiver common mode input voltage range -5 to +5 V Notes: 1.
