Post-Quantum Cryptography (PQC): New Algorithms For A New Era


Post-Quantum Cryptography (PQC), also known as Quantum Safe Cryptography (QSC), refers to cryptographic algorithms designed to withstand attacks by quantum computers. Quantum computers will eventually become powerful enough to break public key-based cryptography, also known as asymmetric cryptography. Public key-based cryptography is used to protect everything from your online communications... » read more

Package Propagation Delay Dependency Of Advanced Fly-By Routing For Next Generation DDR5


Package signal transit delay is an important parameter for high-speed designs like DDR5. Package delay along with PCB delay dictates the data rates of DDR5 interface running at 4.0 Gbps and beyond. From DDR3 (third generation DDR) onwards, daisy chain routing has been widely used as it can support high data rate operations by providing smaller trace stubs and capacitive loadings. Even so, beyon... » read more
