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

Stretching Engineers


Engineering has one constant — you innovate or fall by the wayside. That is true both for the things that are designed and for the engineers who design and build them. Today’s systems are putting new strains on engineers who can no longer be "tall and thin" or "short and fat." Those descriptions pertain to an engineer who is either highly specialized or one who has much broader experience. ... » read more
