3.3V Radiation Tolerant MIL-STD-1553 Transceiver/Transformer Device

SPACE-PHY Dual MIL-STD-1553 Transceiver/Transformer

Data Device Corporation (DDC) introduces a new +3.3V version of our radiation tolerant SPACE-PHY Dual MIL-STD-1553 Transceiver/Transformer Device. SPACE-PHY, now available in both 3.3V and 5V versions, is a completely integrated MIL-STD-1553 physical layer in a single package, including dual transceivers and transformers, and is designed to connect with IP incorporated in an FPGA or custom MIL-STD-1553 protocol ASIC. The SPACE-PHY features an extended -55°C to +125°C temperature range, and 300 krads TID (Total Ionizing Dose) and >85 MeV SEE (Single Event Effects) radiation hardening, required for the extreme environmental conditions encountered in mission critical space applications.

Dual MIL-STD-1553 Transceiver Transformer


  • Compact integrated design saves space… replaces two transceivers and two transformers
  • Single package simplifies layout and improves reliability (MTBF)
  • Transformers and transceivers, trimmed and tested as a set, provide superior margin for MIL-STD-1553 compliance
  • High reliability (Class H & K) screening, including:
    • 100% non-destructive wire bond pull
    • Condition “A” visual inspection
    • Particle Impact Noise Detection (PIND) testing
    • Radiographic (X-ray) inspection
    • 320-hour burn-in

“To support expanding low voltage networking requirements in radiation and space environments, DDC introduces the new 3.3V SPACE-PHY, providing an integrated Class H or K certified MIL-STD-1553 solution” stated Mike Hegarty, DDC’s Data Bus Product Line Manager.
