Clock distribution card brings systems
together
Novel cPCI/PCI clock distribution card features two low-skew signal connector banks, each with one input and 17 clock outputs.
Connecting and synchronising the clocks of large numbers of CompactPCI and standard PCI boards can be a problem when you need the flexibility of having some cards connected while leaving others independent in functionality Now Dataquest Solutions provides a novel cPCI/PCI clock distribution card with two low skew signal connector banks, each with one input and 17 clock outputs

Acquisition range takes on demanding applications
The Spectrum PCI ultra-high-speed board range is claimed to push forward the boundaries of PC-based data acquisition and waveform generation.
With this arrangement each external clock can be distributed to 17 other cards.
This provides a choice as to which cards to connect.
By this method all cards or subsets of cards can be synchronised, plus it makes for the advantage of a neater wiring system.
The clock on each connector bank can also be synchronised and controlled by a user trigger signal.
The special clock distribution card can also be used to clock completely separate numbers of instrumentation racks or PC's.
For systems where all cards are synchronised together Dataquest also offers the nil-skew "star-hub" option where internal ribbon cables feed the clock and trigger to all cards and onto further systems if required.
As with the clock distribution card the signals can be routed to different types of boards, thus producing large mixed functionality systems with hundreds of high-speed channels.
