Product Description
This PTP PCI Express slot card is the best choice for adding a highly accurate time base to your servers or workstations over a simple Ethernet connection. The time source for the card is a IEEE1588 grandmaster clock like the LANTIME M600/GPS/PTP. In the past, sub-microsecond accuracy in PCs could be achieved with GPS synchronized devices only but now with PTP there is no need for complex antenna cabling to every PC.
The integrated single board computer (SBC) is running the PTP stack and provides a PCI Express interface that is compatible with other Meinberg PCIe devices. In this way the board PTP270PEX can be operated by using the standard Meinberg driver package and there is no need to run a PTP software on the computer.
The card can be used as a stratum 0 reference time source for NTP and transforms any machine into a Stratum 1 NTP server without consuming additional physical space in your server room.
Being the first PCI Express PTP V2 compatible timing device on the market, the PTP270PEX comes with a truckload of features to enable software developers to overcome the timing limitations of COTS operating systems like Linux or Windows. The powerful and highly functional Meinberg API (Application Programming Interface) delivers an easy to use and portable way of accessing all Meinberg bus level timing devices. The Meinberg SDK can be downloaded free-of-charge.
Legacy interfaces like IRIG DCLS, 1PPS or 10 MHz can be used to connect other equipment to the PCIe slotcard and transfer the time base over dedicated cable connections to systems which cannot be synchronized via NTP or other network protocols.
The memory mapped access feature offers a fast, simple and efficient way of reading the board time with high precision at very high rates.
The device is designed to be a timing device only and cannot be used as a standard network interface card.
The Windows driver package includes a time synchronization service which runs in the background and adjusts the Windows system time continuously and invisibly. This package also includes a monitor program to enable the user to check the status of the device and time adjustment service. If the monitor program is run with administrator rights, it can also be used to modify configurable parameters.
The Linux and FreeBSD driver packages include a kernel driver which allows the product to be used as a reference time source for the NTP daemon included in most Unix-like operating systems. This also allows the computer to be used as an NTP time server to provide accurate time to NTP clients on the network. Some command line tools can be used to modify configurable parameters and monitor the status of the clock in use.
