Abstract
This paper provides a description of our Network Time Interface M-Module (NTI) supporting high-accuracy external clock synchronization by hardware. The NTI is built around our custom Universal Time Coordinated Synchronization Unit VLSI chip (UTCSU-ASIC), which contains most of the hardware support required for interval-based clock synchronization: A state and rate adjustable clock device with a high resolution, automatically maintained accuracy intervals, interfaces to GPS receivers, and various timestamping features. Designed for maximum network controller and CPU independence, our NTI provides a turn-key solution for adding synchronized clocks to distributed real-tune systems built upon hardware with M-Module interfaces.
This research is part of our project SynUTC, which has been supported by the Austrian Science Foundation (FWF) under grant P10244-ÖMA, the OeNB under grant 6454, the BMWV under contract Z1.601.577/2-IV/B/9/96, and the START programme Y41-MAT.
