Overview
Highly mature, silicon proven and silicon agnostic IP core conforming to CPRI 7.0 specifications
The Common Public Radio Interface (CPRI) 7.0 core is a silicon agnostic implementation of the CPRI 7.0 specification, which is targeting both ASIC and FPGAs CPRI. CPRI is a high-speed serial interface designed to meet or exceed the requirements of base band systems, C-RAN switches, Digital Front-End (DFE) processors or advanced test systems. With its extreme flexibility and reduced logic consumption, the CPRI 7.0 IP core is the perfect match whether the application is REC (Radio Equipment Controller) or RE (Radio Equipment).
The core can be dynamically configured to handle wireless multi-mode radio systems implementing deterministic latency features and high-performance throughputs required by LTE-A and 5G radio base stations.
The CPRI cores come in several versions to suit any implementation scenario whether speed, a compact size or a wide feature set is required.

This article will introduce the main concepts of the Digital Intermediate Frequency Interoperability (DIFI) standard including the new features introduced in version 1.3. With no assumptions of prior knowledge from the reader this should serve as an introduction to the standard but also for those familiar with DIFI raise awareness of the added features of link establishment in new standard version.
This paper describes a method of using Mu-Law compression for Gaussian-like waveforms – for example, baseband IQ data, as used in CPRI interfaces.
At the recent ECOC 2025 conference in Copenhagen, Cadence showcased its key role in enabling the future of AI infrastructure with live silicon demonstrations of several essential IP technologies for emerging 800G and 1.6T networks. Powered by Cadence's 224G SerDes IP, Cadence's Ultra Accelerator Link (UALink 1.0) scale-up and Ultra Ethernet scale-out networking solutions deliver the performance, flexibility, and interoperability needed for next-generation AI factories and hyperscale data centers.
With 5G being deployed for time-sensitive applications, security is becoming an important consideration. At the same time, Open Radio Access Networks (RAN) are gaining more interest from mobile carriers and governments. Yet, Open RAN networks have serious security challenges, especially in the RAN fronthaul where there are strict timing requirements. This paper proposes MACsec as an efficient data link layer security solution that can assist in meeting these challenges.
The following sections will take a look at the major Ethernet performance issues and how the extensions address those shortcomings. This will be followed by an overview of the applications of TSN for 5G, industrial automation, automotive invehicle communications and avionics. The paper will conclude with a description of Ethernet TSN solutions offered by Comcores.
Carriers are now deploying 5G across the globe driven by the need to keep up with relentless mobile data growth. 5G New Radio (NR) operates at higher frequencies to increase bandwidth, but at the expense of range. There will therefore be a need for a much larger number of 5G RUs to provide the same coverage. The availability of cost-effective, reliable and open 5G radio units is therefore critical.
