Microchip’s plug-in timing module targets data centres, 5G and AI connectivity
As data centres and 5G networks become the backbone of AI-driven innovation and digital transformation, the need for precise, resilient timing solutions has never been more critical. Timing is not just a technical requirement, but rather a strategic enabler for high-performance, scalable infrastructure. Microchip has announced its MD-990-0011-B family of plug-in timing modules, delivering turnkey, high-precision synchronisation for data centre servers and 5G virtualised Radio Access Networks (vRAN).
Developed in collaboration with Intel, the MD-990-0011-B timing module is designed for seamless compatibility with Intel® Xeon® 6 SoC-powered server platforms, supporting both OEMs and ODMs in building future-ready systems. By leveraging Intel’s foundational vRAN architecture, the module enables robust, low-latency time synchronisation, which is essential for distributed AI workloads and real-time applications.
Engineered for the reliability and scalability required by cloud infrastructure, virtualisation and high-availability deployments, the MD-990-0011-B supports automatic source selection and locking across Global Navigation Satellite Systems (GNSS), Synchronous Ethernet (SyncE) and Precision Time Protocol (PTP). This flexibility supports continuous, accurate timing even as network demands evolve.
The MD-990-0011-B timing modules are available in two variants. The MD-990-0011-BC01 offers 8-hours of holdover performance, while the MD-990-0011-BA01 offers 4-hours of holdover performance. These timing modules consolidate several of Microchip’s advanced technologies into a single, highly integrated solution.
Key components include:
• Synchronous Ethernet (SyncE) Synthesizer (ZL80132B): Features two independent Digital Phase-Locked Loop (DPLL) channels for flexible and resilient synchronisation
• Oven Controlled Crystal Oscillators (OCXOs, OX-22x): Engineered to provide up to 8-hours of holdover, ensuring stable timing during GNSS outages or network disruptions
• MCP9808 Temperature Sensor supporting enhanced, environmental monitor, 24LC024 EEPROM implementing board configuration and VC-820 for low jitter performance
By unifying these critical timing components into a single plug-in module, the MD-990-0011-B streamlines server architecture, reduces design complexity and simplifies the supply chain. Its modular design enables rapid installation and simplified maintenance, minimising downtime and facilitating effortless upgrades, key advantages for dynamic data centre and 5G network environments.
