CompactPCI  IEEE 1394 High Performance Serial Bus (FireWire™) Host Adapter
400Mbps Open Host Controller Interface

The EKF CF2-CYMBAL is a 3U CompactPCI® hostadapter for the 400Mbps IEEE 1394a-2000 High Performance Serial Bus - also known as FireWire™ (Apple) or i.LINK™ (Sony). The CF2-CYMBAL is based on the OHCI standard (Open Host Controller Interface), supported by all popular operating systems such as Linux und Windows®. The hostadapter provides connectors for up to three 1394 peripheral devices or bus segments.

Isochronous data packets are issued on the average of each 125us in support of time-sensitive applications, which makes the IEEE 1394 High Performance Serial Bus very popular in vision systems (digital video). A high quality video signal e.g. generates an uncompressed continuous data flow of up to 200Mbps, which is passed across the CF2-CYMBAL just-in-time to the CompactPCI system.

CF2-CYMBAL - Triple Port 400Mbps IEEE 1394 OHCI Host Adapter

The CF2-CYMBAL is housed on a 3U (single size) Eurocard. With its triple 1394 cable port, the board can be operated as a controller (master) and transceiver. For 6U systems, EKF offers a mechanical adapter kit to expand the front panel of the CF2-CYMBAL to the full 6U height.

The board is based on a Texas Instruments OHCI-Lynx link layer controller and PHY, which operate at data transfer rates up to 400Mbps, compliant to IEEE 1394a-2000. All three ports use 6-lead Molex connectors with cable power distribution.

The CF2-CYMBAL requires no proprietary software but OHCI compliant drivers, which are integral and reliable part of all popular operating systems.

Hence the IEEE 1394 CompactPCI hostadapter CF2-CYMBAL is suitable for a wide range of industrial applications, typically image based control systems with real-time demand, such as vision- and inspection systems, e.g. AOI (automated optical inspection), production control, or traffic monitoring (toll recording).
