Meinberg, a leading manufacturer of time and frequency equipment, announced the general availability of the first GPS time receiver for the PCI Express bus. The new GPS170PEX adds highly accurate and reliably time stamping capabilities to any server or workstation with a free PCIe single lane slot.

Meinberg Funkuhren GmbH & Co. KG, a leading German manufacturer of time and frequency equipment, today announced the general availability of the world's first GPS time receiver for the PCI Express Bus.

The new GPS170PEX offers the same feature set of the PCI-X version plus introduces a memory mapped access feature that allows to read timestamps in a very fast and accurate way.

By providing legacy timing signals like IRIG, 1PPS or serial time strings, the GPS170PEX can be used to synchronize additional systems without the need for a network connection. Using freely available software like NTP or the Meinberg Time Service, the slot card can be used to synchronize the system time of the host PC and, by running NTPD, provide time synchronization to other PCs and embedded (S)NTP clients over a standard network connection.

The GPS170PEX is the latest addition to Meinberg's range of PCI Express slot cards. The TCR511PEX IRIG Time Code Reader as well as the PEX511 DCF77 Radio Clock are also available for PCIe systems.

The "Single Driver" concept of Meinberg greatly simplifies deployment and installation of different slot cards, because there is only one driver needed to support all Meinberg bus level products, including ISA, PCI, PCI-X, PCIe and USB devices. The Meinberg API can be used to add highly accurate timestamps to applications like data acquisition, network monitoring and performance measurement. By supporting all cards with the same API calls, it is very easy to write portable code which can be used with different generations of timing receivers and even different reference time sources like IRIG or GPS.

Typical uses are inclusion in data acquisition and measurement stations in the financial sector, military, telecom industry, information technology and research and science projects.
