Integrated Device Technology, Inc. introduced the industry’s first integrated Serial Presence Detect (SPD), temperature sensor and control plane hub component (referred to as “SPD Hub”) developed for DDR5-based Dual In-Line Memory Modules (DIMM). The IDT SPD Hub is designed to provide a space and power efficient solution that enables control plane operation at significantly higher speeds than previous system management buses with enhanced reliability.
As system speed, bus utilization, and component count continue to grow in DDR5-based systems, control plane speed and scalability will be critical to system performance and reliability. The system control plane supports such functions as initialization, temperature control, security, and lights-out management.
The IDT SPD Hub is the center for control plane communication between DIMM components such as the registered clock driver (RCD), power management IC (PMIC) and thermal sensors and system management devices such as the central processor or baseboard management controller (BMC). IDT’s SPD Hub allows the DDR5 system control bus to scale significantly beyond previous generations and enables a new class of data center equipment.
Samples of the IDT DDR5 SPD Hub are available now to select customers and partners.
