3D PLUS has more than 200,000 microelectronics components in space, and more than 20 years of flight heritage with no reported failure. Our Flight Heritage is expanding continuously with products launched in Space every month in LEO, MEO and GEO orbits, for deep space exploration missions, for satellite constellation fleets, and for governmental missions in Europe, America, and Asia. Our Flagship missions include Mars 2020, Mars Science Laboratory, Rosetta, New Horizons, Juno, OneWeb, AlphaSat, Sentinel, Ariane 5, ISS, Parker Solar Probe, Insight, and many more.
The DDR2, 3 and 4 Termination Regulator (TR) modules are compact and flexible, Rad-Hard-by-Design for low input voltage, low-noise Double Data Rate (DDR) memories. TR modules maintain fast transient response times; offer a remote sensing function; support control via Command pin and provide all power requirements for DDR VTT bus designs.
By incorporating radiation effect mitigation techniques, they are the perfect solution to be used with DDR memories in high reliability applications.
TR modules are manufactured with 3D PLUS’s Space qualified stacking technology designed for high reliability applications, and is available in a compact, low weight package.
Tightly regulated voltage on VTToutput (JEDEC compatible)
Eliminates the need for external output capacitors
Source and Sink current capability of ±1A (DDR2 TR) or ±2A (DDR3 TR and DDR4 TR)
Radiation Hardened design:
