Symmetricom, Inc. (NASDAQ: SYMM), a worldwide leader in precise time and frequency products and services, today announced its XLi IEEE 1588 Grandmaster Clock with GPS (Global Positioning System) reference for IEEE 1588 protocol test and measurement applications. IEEE 1588 protocol enables very accurate synchronization over Ethernet LANs and offers users the ability to synchronize clocks to better than one hundred nanoseconds accuracy with only a network connection. The XLi IEEE 1588 Grandmaster provides the precise time and is also equipped to physically measure how well that time is transferred through the network with precision down to five nanoseconds resolution.

"Symmetricom is the first to offer an IEEE 1588 test and measurement solution to help customers verify the performance of IEEE 1588 products in their networks," commented Paul Skoog, product marketing manager at Symmetricom. "Customers need a tool to know if the high precision and accuracy possible with IEEE 1588 equipped products is actually working in their networks. The XLi Grandmaster is just the tool to measure time transfer accuracy through network elements such as switches or through custom network topologies."

The XLi Grandmaster can provide the time to a 1588 slave clock and measure the resulting accuracy. This is useful to characterize both the slave clock and the network topology between the Grandmaster and the slave. The XLi Grandmaster also measures time degradation through hubs and switches, characterizing them before deployment in an operational network. When an inconvenient distance separates the XLi Grandmaster from the slave, using GPS as a common and precise time reference enables very accurate and easy one-way path latency testing not easily achieved any other way. One XLi Grandmaster operates as the source of time, and the other XLi Grandmaster measures the slave accuracy at the remote end of the network.

The Boeing Company was the first customer to deploy the XLi IEEE 1588 Grandmaster clock. Implemented in the new 787 network based flight test data system, Boeing chose the XLi due to its modularity and Symmetricom's commitment to Boeing to deliver IEEE 1588 functionality.

Availability

The XLi IEEE 1588 Grandmaster Clock with GPS is currently shipping.
