PISCATAWAY, N.J., March 06, 2025 (GLOBE NEWSWIRE) — The Digital Intermediate Frequency Interoperability Consortium (DIFI) announced that it has completed work on version 1.2.1 of its interoperability standard (IEEE-ISTO Std 4900-2021). According to DIFI chairman Stuart Daughtridge, the new version of the Standard is a significant improvement in the areas of sync and flow control over the previous version, which was published in August 2023.
As more companies become DIFI-compatible, the consortium’s members have formed a full ecosystem and are set to show their products and technologies, including digitizers, modems, test equipment, signal monitoring systems and virtual ground systems at SATELLITE 2025 in Washington. The transition to truly interoperable digital ground systems is now easier since the industry’s supply chain has DIFI-compatible versions of all necessary equipment, Daughtridge added.
According to DIFI, version 1.2.0 added a standard flow control mechanism, which frees up systems designers from proprietary data flow for buffer management and improves timing synchronization. These changes were enabled by a new Information Class (0x0002) and new Packet Classes (0x0002, 0x0003, 0x0005 and 0x0006).
