Creonic Releases Updated SDA OCT IP Core Supporting OCT 4.0 and Enhanced Synchronization

Kaiserslautern, Germany -- January 06, 2026 -- Creonic GmbH, the leading provider of ready-for-use IP cores for communication systems, announces an updated version of its SDA OCT IP Core. The new release introduces architectural improvements and extends standard support to simplify system integration and supporting both current and future Optical Communications Terminal (OCT) deployments that have been standardized by the Space Development Agency (SDA).

The updated SDA OCT IP Core now operates in a single clock domain, reducing design complexity and easing integration into FPGA-based systems. It adds flexible frame synchronization with configurable parameters, allowing adaptation to different links and system requirements. Timestamp passthrough functionality enables precise time alignment while intentionally omitting internal timestamp synchronization logic, supporting system-level timing concepts without imposing architectural constraints.

Resource utilization has been further optimized to enable efficient implementations on target platforms. The IP core is compatible with SDA OCT 3.1.0 as specified in Document ID SDA-9100-001-08 (March 2024) and is fully compliant with the Optical Communications Terminal (OCT) Standard Version 4.0.0, Document ID SDA-9100-001-09 (August 2024). Backward compatibility with SDA OCT 3.0 is maintained, ensuring continuity for existing designs.
