High-Precision Plug-in Modules for Data Center and 5G Synchronization

The MD-990-0011-B family of plug-in timing modules provides high-precision frequency and time synchronization for data center infrastructure and 5G virtualized Radio Access Networks (vRAN). These modules are specifically designed for compatibility with Intel Xeon 6 SoC-powered platforms to support low-latency requirements in distributed AI workloads and cloud virtualization.

Integration with the Digital Supply Chain
The MD-990-0011-B streamlines the digital supply chain by consolidating complex timing components — including synthesizers, oscillators, and sensors — into a single, modular hardware unit. This plug-in approach replaces the need for custom, discrete timing circuits on the motherboard, allowing Original Equipment Manufacturers (OEMs) and Original Design Manufacturers (ODMs) to reduce hardware development cycles.

By utilizing a standardized interface, the module facilitates rapid installation and simplifies maintenance protocols in high-availability environments. This modularity allows system administrators to upgrade timing capabilities or replace components without redesigning the primary server architecture, addressing the evolving needs of the automotive data ecosystem and edge computing where timing precision is a primary constraint.

Technical Mechanisms and Standards Support
The hardware architecture utilizes several integrated technologies to maintain synchronization across varied network conditions. The module supports automatic source selection and locking, enabling it to transition between multiple timing references to ensure continuous operation. Support for established industry standards includes:

The core of the module features the ZL80132B SyncE synthesizer, which utilizes two independent Digital Phase-Locked Loop (DPLL) channels. This dual-channel configuration provides the redundancy necessary for resilient network synchronization. Furthermore, the inclusion of the VC-820 ensures low-jitter performance, which is critical for maintaining signal integrity in high-frequency 5G transmission.

Holdover Performance and Environmental Stability
To mitigate the impact of GNSS outages or network disruptions, the MD-990-0011-B employs OX-22x Oven Controlled Crystal Oscillators (OCXOs). These components are engineered to maintain timing stability through high-precision holdover capabilities. The product family is offered in two distinct performance tiers:

Environmental monitoring is managed by the MCP9808 temperature sensor, which tracks thermal fluctuations to compensate for frequency drift. Board configuration and identification are handled by an onboard 24LC024 EEPROM, ensuring the module is correctly recognized and initialized by the host Intel Xeon 6 SoC system. According to Randy Brudzinski, corporate vice president of Microchip’s frequency and time systems business unit, this plug-in solution allows designers to address timing requirements proactively during initial builds or as field upgrades, effectively removing the complexity associated with custom timing circuitry.
