PCI Express is the latest implementation of the PCI bus, which is only software-compatible with other PCI bus specifications. The PCI Express hardware layout is totally different (it is not possible to install a PCI Express card in a PCI/PCI-X slot or vice-versa).

Meinberg offers PCIe timing devices for computer and network synchronization in both low-profile and regular sizes.

Product Description PCIe Clocks

PCI Express has been designed to yield a high transfer rate across a low number of data lines, and is based on a high speed serial protocol similar to LAN or IEEE1349 (Firewire) connections. A single PCI Express slot can implement several such „lanes“ in parallel to multiply the transfer rate of a single lane.

The serial port can be used to update the card’s firmware, and connected to a computer serial port to use the card as reference time source in operating systems where a serial time string is supported but no kernel device driver is available (such as NTP).

To use a MEINBERG PCIe Clock in your own application, please download our software development kit (SDK) which contains libraries and sample code and shows how to access the card from within your software.

All drivers and API sample source code can be downloaded free of charge from our website, and we are glad to assist you if experience any difficulty using the Meinberg driver API in your software development process.

Overview: PCIe Clocks

GPS180PEX
Low Profile GPS Clock (PCI Express)

The board GPS180PEX is designed as a low profile board for computers with PCI Express interface. The rear slot cover integrates the antenna connector, a BNC connector for modulated time codes, a 9pin D_SUB male connector and two status LEDs. With this standard height bracket you can use the D_SUB connector for I/O signals like RS-232 - PPS and PPM and you can use this interface for firmware updates.

The GPS180PEX is delivered including a low profile bracket. You can mount this part instead of the standard bracket, to run the GPS180PEX in computers with smaller housing (e.g. 1U server).

GNS181PEX
Low Profile GPS / GLONASS / Galileo / BeiDou Clock (PCI Express)

The board GNS181PEX is designed as a low profile board for computers with PCI Express interface. The rear slot cover integrates the SMA antenna connector, a BNC connector for modulated time codes, a 9pin D-SUB male connector and four status LEDs (2mm light pipes). With this standard height bracket you can use the D-SUB connector for I/O signals like RS-232 - PPS and PPM and you can use this interface for firmware updates.

The GNS181PEX is delivered including a low profile bracket. You can mount this part instead of the standard bracket, to run the GNS181PEX in computers with smaller housing (e.g. 1U server).

The integrated GNSS receiver requires an external antenna. It can be configured to use GPS, Galileo, Beidou and GLONASS. The configuration allows the user to select one of these sources to be used exclusively or a combination with up to three of these sources:

-GPS

-GLONASS

-BeiDou

-GPS + GLONASS

-GPS + BeiDou

-Galileo

-GPS + Galileo

-Galileo + GLONASS

-Galileo + BeiDou

-GPS + Galileo + GLONASS

-GPS + Galileo + BeiDou

PZF180PEX
Low Profile DCF77 Clock (PCI Express)

The board PZF180PEX is designed as a low profile board for computers with PCI Express interface. The rear slot cover integrates the antenna connector, a BNC connector for modulated time codes, a 9pin D_SUB male connector and two status LEDs. With this standard height bracket you can use the D_SUB connector for I/O signals like RS-232 - PPS and PPM and you can use this interface for firmware updates.

The PZF180PEX will be delivered with a low profile bracket. You can mount this part instead of the standard bracket, to run the PZF180PEX in computers with smaller housing (e.g. 1U server).

TCR180PEX
IRIG Time Code Receiver and Generator for Computers (PCI Express)

The TCR180PEX receives

IRIG-A/B/G, IEEE 1344, IEEE C37.118 or AFNOR NF S87-500 time codes

and can be used for synchronizing the system time of its host PC. The output of this card can generate an IRIG signal for other IRIG time code readers. The output format is independent from the incoming IRIG signal - a perfect solution to your IRIG conversion requirements.

TCR180PEX-EL
IRIG Time Code Receiver for Computers (PCI Express)

The TCR180PEX-EL receives

IRIG-A/B/G, IEEE 1344, IEEE C37.118 or AFNOR NF S87-500 time codes

and can be used for synchronizing the system time of its host PC.
