FPGA CoaXPress IP Core – Device

Applications

KAYA Instruments’ CoaXPress Device IP Core provides a multi-link transmitter solution for high-bandwidth cameras and imaging systems. It supports CoaXPress v2.0, with backward compatibility to v1.1, and GenICam-compliant image formats for area-scan, line-scan, multi-ROI and multi-sensor applications.

The device IP provides a configurable video streaming interface and pixel packer for direct connection to imaging sensors or user logic. Coaxial implementations support link rates up to 12.5 Gbit/s, depending on the FPGA and configuration, with up to four links as standard and additional links available on request.

CoaXPress over Fiber support

For optical connectivity, combine the Device IP Core with KAYA Instruments’ Multi-Link Device CoaXPress over Fiber Bridge. The bridge carries CoaXPress traffic through an XGMII interface to a compatible 10G Ethernet physical layer, enabling fiber-based camera-to-frame-grabber connections.

• Support for one to four parallel fiber links.
• A 10 Gbit/s interface per link with an effective bit rate equivalent to CXP-12 without the coaxial link’s 8b/10b encoding overhead.
• High-speed image-data transmission from the device and low-speed control reception from the host.
• Implementation based on the CoaXPress over Fiber Bridge Protocol v1.0 (JIIA CXPR-008-2021); integration requirements and protocol exceptions are documented in the CoF Bridge manual.

The documentation includes a dedicated Device CoF Bridge manual and a Device CXP-to-Fiber integration appendix. The appendix applies to Device CXP IP v7.0.5 and later; earlier versions require additional auxiliary logic. Select the FPGA, physical layer and optical components for the required link configuration.
