Overview
QSGMII (Quad Serial Gigabit Media Independent Interface) IP from Comcores is a high-speed serial interface developed to aggregate four Gigabit Ethernet (SGMII) ports into a single high-speed serial link using 8b/10b encoding at 5 Gbps. It reduces the number of physical connections needed between Ethernet MACs and PHYs contributing to lowering power and cost.
The IP is compliant with IEEE 802.3, SGMII, QSGMII (as defined by Broadcom) and is targeting ASIC’s and has gone through full UVM verification and is silicon proven.

How to cost-efficiently add Ethernet switching to industrial devices
This post explores critical considerations and solutions for implementing Ethernet switches tailored to industrial applications, emphasizing required features and cost-effectiveness.
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.
MACsec for Deterministic Ethernet applications
Why MACsec is a compelling security solution for Deterministic Ethernet networks and how Packaged Intellectual Property solutions can accelerate time-to-market for chip developers
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.
Accelerating 5G virtual RAN deployment
This whitepaper provides an overview of the O-RAN Alliance and the value provided by O-RAN to the carrier industry along with a brief introduction to Comcores, our O-RAN solutions and our role in the O-RAN eco-system.
