Network synchronization unit
SEMTECH
Semtech Timing over Packet Synchronization (ToPSync™) use the IEEE 1588 V2 Precision Time protocol to transport time or frequency over pack-based networks. This technology seamlessly enables packet networks to move to providing services more traditionally carried over circuit based networks such as SONET & SDH. This technology uses a very low data rate (typically 8kb/s) to deliver frequency, phase or time alignment with precision rivaling a typical GPS receiver. Our implementation of the IEEE 1588 V2 protocol is fully compatible with all Ethernet or IP networks. In addition, TopSync can supply FDD/TDD radio systems and circuit emulation systems with the synchronization signals they need -- greatly reducing the cost of clocking all wireless basestation equipment. Interoperability is ensured with ToPSync's compliance to all the relevant parts of IEEE 1588 V2.
