MIL-STD-1553 transceivers that offer the industry’s lowest power consumption and dissipationis based on discrete components.
Another key point is that Sital’s transceivers use state of the art power switching devices which reduce the output stage power dissipation to less than 300 mW when transmitting at 100% duty cycle.
Also, when used with matching isolation transformers, the transceivers comply with MIL-STD-1553B and MIL-STD-1760, and have passed MIL-STD-1553 validation testing.
In addition, Sital’s transceivers include a mechanism to absolutely minimize or eliminate residual voltages, aka “dynamic offset” or “tails” at the end of message transmissions.
Even more, this feature enables error-free transmission for bulk data transfer applications involving large numbers consecutive messages with up to 32 data words.
Sital’s SIT-1579 is a fully compliant MIL-STD-1553 and MIL-STD-1760 transceiver. It is available in both industrial (-40 to +85° C) and military (-55 to +125° C) temperature ranges and packaged in a 20-pin SOIC.
Coupled with the fact, Sital can supply either packaged transceivers or transceiver design IP. The transceiver IP is supplied as design documentation. Since both the packaged transceivers and the transceiver IP involve the use of COTS components, they provide Sital and its customers the freedom to choose components from multiple vendors. In addition to mitigating against obsolescence, this provides capability to shop for best price, delivery and optimized temperature ranges for specific applications.
For use with its MIL-STD-1553 transceivers, Sital also offers a line of low-cost non-QPL isolation transformers complying with MIL-PRF-21038/27E electrical specifications. The transformers are drop-in replacements for industry standard transformers. These are available in multiple configurations including single and dual, through-hole and surface mount, and support for either transformer-coupled only or both transformer-coupled and direct-coupled configurations.

MIL-STD-1553/1760 transceiver/transformer combo.
MIL-STD-1553/1760 transceiver/transformer combo, firstly the SIT-2579 is a dual-channel transceiver.
This integrated solution is based on the design of the SIT-1579 dual transceiver, hence a dual isolation transformer.
Furthermore, the SIT-2579 transceiver operates in conjunction with Sital’s 1553 digital IP instantiated in an FPGA or ASIC.
Sital’s SIT-1579 is a fully compliant MIL-STD-1553 and MIL-STD-1760 transceiver. Available in both industrial (-40 to +85° C) and military (-55 to +125° C) temperature ranges and packaged in a 20-pin SOIC, it’s a second source to Holt’s HI-1579 transceiver. Based on discrete components, the CMP1553XVR uses state of the art power switching devices which reduce the output stage power dissipation to less than 300 mW when transmitting at 100% duty cycle. The transceiver requires no special heat dissipation pads.
In addition, the SIT-1579 includes a closed loop mechanism for minimizing or eliminating residual voltages; aka “dynamic offset” or “tails” at the end of message transmissions. This feature is highly beneficial for eliminating data errors for situations involving a terminal transmitting long sequences of 32-word messages.
MIL-STD-1553 transceiver. Sital’s DES1553XVR is a designed IP for a fully compliant MIL-STD-1553 transceiver.
Firstly, the DES1553XVR‘s deliverables include a schematic, parts list and PC board layout guidelines. Since the transceiver design consists of discrete parts, it provides obsolescence mitigation along with the flexibility to shop from multiple suppliers.
In addition, it provides board layout flexibility to enable use in very tight board designs. In addition to MIL-STD-1553 the same design can also support other protocols including H009, MIL-STD-1760, 16PP194 and others.
The BRD1553XVR(-P) board provides a complete physical layer solution for MIL-STD-1553 and MIL-STD-1760. For IP development, this daughterboard may be used to interface between an FPGA development board and a MIL-STD-1553 or MIL-STD-1760 bus. The board includes a dual 1553 transceiver and dual transformer, with capability to select for either direct-coupled or transformer-coupled stub connections. The BRD1553XVR-P configuration of the board includes a PMOD connector for the transceiver digital signals and a pair of triax connectors for the 1553 bus signals.
