Understanding SerDes Signal Integrity Challenges


Signal integrity (SI) can perhaps best be defined as a set of measures of the quality of electrical signals, which are subject to the effects of noise, distortion and loss. Additional signal integrity issues include jitter, ringing, crosstalk, ground bounce and power supply noise. There are multiple factors that can negatively influence signal integrity, thereby causing errors and system fai... » read more

HBM2: It’s All About The PHY


HBM DRAM is currently used in graphics, high-performance computing (HPC), server, networking and client applications. HBM, says JEDEC HBM Task Group Chairman Barry Wagner, provides a “compelling solution” to reduce the IO power and memory footprint for the most demanding applications. Recent examples of second-generation HBM deployment include NVIDIA’s Quadro GP100 GPU which is paired wit... » read more
