MIL-STD-1553/1760 transceiver CMP1553XVR is a
module based on the SIT-1579 transceiver design with
discrete components assembled on a daughter.

Pin compatible with HOLT’s HI1579 monolithic
transceiver.

The CMP1553XVR/SIT-1579 interfaces between the digital
domain signals from the FPGA 3v3 signals and the MIL-STD-1553 transformer.

A key point is by using discrete components, the CMP1553XVR/SIT-1579 uses state of art power switching devices which reduce the power dissipation to a record of 0.25W when transmitting 100% of the time.

As a result, no special heat dissipation pads needed.
This transceiver design CMP1553XVR/SIT-1579 is delivered in 20 PIN QFN PCB that fits the PCB foot print of the HI-1579 SOIC-20.

CMP1553XVR/SIT-1579 presents a breakthrough in
transceiver design in a number of ways.

In terms of cost, standard 1553 COTS transceivers require special manual &
costly symmetry alignments for every component going off the fabrication line.

The SIT-1579 on the other hand does not
have any such alignment during fabrication, but rather
online.

Once the power is engaged, and during each and
every transmission. This dynamic alignment balances and
eliminates the symmetry issues that are common with
1553 transceivers resulting in higher quality signaling at a
lower cost.

A typical 1553 COTS transceiver comprises of a digital part and an analogue part, and the CMP1553XVR/SIT-1579 only contains the analogue parts.

In particular, the digital is embedded inside the FPGA. The FPGA digital part of the transceiver manages the symmetry alignment in addition to noise filtering and short detection. Sital Technology and Hardware Engineering, Ltd. is a Xilinx Partner (xilinx.com)
