According to the company when combined with SiTime’s oscillators and clocks, TimeFabric can deliver up to 9X more accurate time synchronisation than quartz-based solutions, enabling much higher system performance and utilisation in AI data centres.
The TimeFabric software suite consists of two modules: IEEE 1588 standards-compliant synchronisation software, as well as proprietary technology to extend critical holdover performance to 24 hours.
In addition to AI data centre applications such as smart network interface cards (SmartNIC), switches, routers and accelerators, TimeFabric can also be used in 5G infrastructure, including remote radio units and base stations, fixed wireless access (FWA) equipment and core network equipment.
The TimeFabric software suite has two software modules:
IEEE 1588 Precision Time Protocol (PTP) Standards-compliant Servo and Stack
SiTime’s servo and software stack for IEEE 1588 precision time protocol (PTP) with sub-nanosecond synchronisation accuracy delivers tighter control and greater timing stability over generic IEEE 1588 solutions. Network architects gain flexibility in network traffic scheduling and load balancing, which will result in higher utilisation.
Holdover Extension Software
TimeFabric’s proprietary holdover extension software can be used to enhance the functionality of SiTime’s precision devices with in-field software upgrades. The holdover extension software delivers up to 24 hours of holdover, essential to mobile and network infrastructure reliability – a stringent requirement for critical infrastructure. This ensures full operation in the event of GNSS outages or network clock failures.
Additional features include:
- IEEE 1588-2019 compliant - meets ITU-T G.8273.2 Class D:
- Full timeTransmitter and timeReceiver capability.
- Hardware timestamping support.
- Device drivers for SiTime network synchronisers.
- IEEE 1588 management support.
- 2X longer holdover:
- Up to 24 hours holdover with SiT5811, SiT5812 or SiT7101.
