CPRI Altera® FPGA IP
The Common Public Radio Interface (CPRI) Altera® FPGA IP core implements the CPRI Specification V7.0.
Overview
The Common Public Radio Interface (CPRI) Altera® FPGA IP core implements the CPRI Specification V7.0. CPRI is a high-speed serial interface for network radio equipment controllers (REC) to receive data from and provide data to remote radio equipment (RE). The IP core targets high-performance, remote radio network applications. You can configure the CPRI Altera® FPGA IP core as an RE or an REC.
Key features
- Compliant with the Common Public Radio Interface (CPRI) Specification v7.0 (2015-10-09) Interface Specification.
- Supports radio equipment controller (REC) and radio equipment (RE) module configurations.
- Configurable CPRI line bit rate auto-rate negotiation support using Altera® FPGA on-chip high-speed transceivers.
- Configurable and runtime programmable synchronization mode: host port or agent port on a CPRI link.
- Transmitter (Tx) and receiver (Rx) deterministic latency and delay measurement and calibration. Note: Compliant with the CPRI Specification requirements R-19, R-20, R-20A, R-21, and R-21A.
- Configurable CPRI communication line bit rate (to 0.6144, 1.2288, 2.4576, 3.0720, 4.9152, 6.144, 8.11008, 9.8304, 10.1376, 12.16512 or 24.33024 Gbps) using Altera® FPGA on-chip high-speed transceivers.

O-RAN Fronthaul Security using MACsec
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.
Seize the Ethernet TSN Opportunity
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.
Part 2: Opening the 5G Radio Interface
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.
