DIGITAL INTERMEDIATE FREQUENCY INTEROPERABILITY DIFI
Bascom Hunter’s Digital Intermediate Frequency Interoperability (DIFI) v1.2 IP Core is a fast-deployable solution to incorporate DIFI support into your system. DIFI is the emerging IEEEISTO Std 4900-2021 standard for transferring RF data, such as digitized ADC and DAC samples, between system components.
DIFI uses a packet structure that simplifies the interoperability and communication of digital RF components from different vendors. Bascom Hunter is a contributing member to the DIFI consortium and has directly participated in feature updates such as the addition of flow control mechanisms.
