The compact and flexible DDR2, DDR3, and DDR4 Termination Regulator (TR) modules are perfect for low input voltage and low-noise Double Data Rate (DDR) memories. These Termination Regulator modules offer fast transient response times, a remote sensing function, and can be controlled via the Command pin. Additionally, they provide all the power requirements for DDR VTT bus designs.
By incorporating radiation effect mitigation techniques, the Termination Regulator modules become the ultimate solution for use with DDR memories in high reliability space applications. Manufactured with 3D PLUS’s Space qualified stacking technology, these modules are specifically designed for high reliability applications. They are available in a compact and lightweight package, making them suitable for various environments.
Experience the benefits of these Rad-Hard-by-Design TR modules with your DDR memories. Improve the performance and reliability of your DDR VTT bus designs with our 3D PLUS expertise. Trust us for high-quality modules that surpass your expectations in high-reliability applications.
