Microchip Technology has released its MD-990-0011-B family of plug-in timing modules, delivering turnkey, high-precision synchronization for data center servers and 5G virtualized 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 synchronization, which is essential for distributed AI workloads and real-time applications.
Engineered for the reliability and scalability required by cloud infrastructure, virtualization and high-availability deployments, the MD-990-0011-B supports automatic source selection and locking across 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. MD-990-0011-BC01 offers eight hours of holdover performance; MD-990-0011-BA01 offers four 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). Two independent digital phase-locked loop (DPLL) channels for flexible and resilient synchronization
- Oven controlled crystal oscillators (OCXOs, OX-22x). Provide up to eight hours of holdover, ensuring stable timing during GNSS outages or network disruptions
- MCP9808 temperature sensor. Supports 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, minimizing downtime and facilitating effortless upgrades, key advantages for dynamic data center and 5G network environments.
