Silicon agnostic, Highly scalable implementation of IEEE-ISTO Std 4900-2021
The DiFi IP core is a highly scalable and silicon agnostic implementation of the IEEE-ISTO Std 4900-2021: Digital IF Interoperability Standard v1.2.1 targeting ASIC, and FPGA technologies. The DiFi implementation builds on long-time experience designing IP cores for sending and receiving Radio IQ data over Ethernet networks, and delivers a flexible engine that is prepared for tight integration with software applications.
Source (Transmitter) and Sink (Receiver) components are provided, allowing for Duplex Equipment communication and supporting both Uplink and Downlink VITA-49 (VMEbus International Trade Association) stream directions.
DiFi IP from Chip Interfaces is designed to meet or exceed the requirements of stationary or mobile Satellite communication Ground Stations. The speed-optimized core can handle any solutions reaching from the “small footprint” to the most complex applications running on 100G Ethernet links.
Chip Interfaces DiFi IP comes with the widest parameter set available and has gone through extensive testing in our UVM regression test environment.
The DIFI IP core interfaces with the UDP IP via the AXI Stream interface, and towards the application with either an AXI MM interface or an AXI Stream interface. The Design consists of both the IF/RF Converter Receive Path and the IF/RF Converter Transmit path, allowing the implementation of both the RF-to-IP and IP-to-RF sides of the communication.
