XIMEA and PCIe

In all our camera designs we strive to propel our core properties: maximum sensor performance, ease and flexibility of integration, power efficiency, and super low latencies. The quest for ever higher bandwidth and extremely fast data processing has led us, as one of the first camera manufacturers, to use the PCIe interface nearly all computers have, to transfer the data from our cameras as quickly and as efficiently as possible.

Why PCIe

Simply put, PCIe has some of the highest bandwidth, lowest possible latency, and scalable architecture for the most demanding imaging applications out there which makes PCIe the ultimate camera interface for high throughput sensors and multi-camera systems. Higher speeds are planned for with upcoming PCIe generations, and sensors continue their march to higher performance leading to yet further innovation in both camera and vision application development.

How does PCIe work?

A PCIe link represents a communications channel between two components. It operates at a specified data rate which is determined by its generation. PCIe devices are generally backward compatible, so a Gen3 device can connect to a Gen2 device using a Gen2 link.

Sensors or Endpoints: Any device (e.g. a camera or sensor) that connects to the root complex through PCIe.
The Connection is the data transfer from the sensor to the next stage. Different options of cables with different throughput, forms etc. are available.
The Integration describes how the signals of several sensors are combined or one sensor is connected to a workstation.

A Switch is a component that creates a bridge from one upstream (i.e. in the direction of the root complex) link to multiple downstream (i.e. in the direction of an endpoint) links. The links on a switch may use different numbers of lanes and different data rates.

A Hostsystem can be a Workstation, a Server, or NVIDIA Jetson SoC or anything the data from the sensor is processed on.

Cabling options:

PCIe ecosystems

PCIe - simple and powerful! PCI Express interface is the backbone of every computer, so using its full potential ensures maximum sensor speed, modularity, power efficiency, and lowest latency.
