Dual Compact MIL-STD-1553 or 1553/1760 Transceiver/Transformer

Products 

Overview

The SIT-2579 interfaces with 3.3V logic signals from an FPGA or digital ASIC instantiating one of Sital’s MIL-STD-1553 IP cores. Based on discrete components, the SIT-2579 uses state of art power switching devices to reduce power dissipation to under 300 mW at 100% transmit duty cycle. This provides the lowest transmitter dissipation in the industry. In addition, no special thermal pads are required for mounting the device.

The SIT-2579 comes in a 16-pad leadless, surface-mount package.

The SIT-2579 transceiver operates in conjunction with Sital’s 1553 digital IP instantiated in an FPGA or ASIC. By means of a real-time closed-loop correction technique, this enables the SIT-2579 to eliminate or minimize transmitter residual voltages, aka dynamic offsets or “tails” at the end of message transmissions. By allowing continuous adjustment to compensate for changes in power supply voltage and temperature, this technique provides improved performance over factory-trimmed transmitters. As a result, the SIT-2579 is ideal for applications requiring the transmission of a series of consecutive 32-word messages.
