This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: As demand for higher bandwidth I/O grows, the front end design of serial link becomes significant to overcome stringent timing requirements on noisy and bandwidthlimited channels. As a clock reconstructing module in a receiver, the recovered clock quality of Clock and Data Recovery is the main issue of the receiver performance. However, from unknown incoming jitter, it is difficult to optimize loop dynamics to minimize steady-state and dynamic jitter. In this thesis a 10 Gb/s adaptive loop bandwidth clock and data recovery circuit with on-chip loop filter is presented. The proposed system optimizes the loop bandwidth adaptively to minimize jitter so that it leads to an improved jitter tolerance performance. This architecture tunes the loop bandwidth by a factor of eight based on the phase information of incoming data. The resulting architecture performs as good as a maximum fixed loop bandwidth CDR while tracking high speed input jitter and as good as a minimum fixed bandwidth CDR while suppressing wide bandwidth steady-state jitter. By employing a mixed mode predictor, high updating rate loop bandwidth adaptation is achieved with low power consumption. Another relevant feature is that it integrates a typically large off-chip filter using a capacitance multiplication technique that employs dual charge pumps. The functionality of the proposed architecture has been verified through schematic and behavioral model simulations. In the simulation, the performance of jitter tolerance is confirmed that the proposed solution provides improved results and robustness to the variation of jitter profile. Its applicability to industrial standards is also verified by the jitter tolerance passing SONET OC-192 successfully.

This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: As the volume of data processed by computers and telecommunication devices rapidly increases, high speed serial link has been challenged to maximize its I/O bandwidth with limited resources of channels and semiconductor devices. This trend requires designers̕ relentless effort for innovations. The innovations are required not only at system level but also at sub-system and circuit level. This dissertation discusses two important topics regarding high speed serial links: Clock and Data Recovery (CDR) and Current Mode Logic (CML). This dissertation proposes a mixed-mode adaptive loop gain Bang-Bang CDR. The proposed CDR enhances jitter performances even if jitter spectrum information is limited a priori. By exploiting the inherent hard-nonlinearity of the Bang-Bang Phase Detector (BBPD), the CDR loop gain is adaptively adjusted based on a posteriori jitter spectrum estimation. Maximizing advantages of analog and digital implementations, the proposed mixed-mode technique achieves PVT insensitive and power efficient loop gain adaptation for high speed applications even in limited ft technologies. A modified CML D-latch improves CDR input sensitivity and BBPD performance. A folded-cascode-based Charge Pump (CP) is proposed to minimize CP latency. The effectiveness of the proposed techniques was experimentally demonstrated by various jitter performance tests. This dissertation also presents a process-variation-resilient CML. A typical CML requires over-design to meet the specification over the wide range of process parameter variations. To address this issue, the proposed CML employs a time-reference-based adaptive biasing chain with replica load. It adjusts a variable load resistor to simultaneously regulate time-constant, voltage swing, level-shifting and DC gain. The performance of the high speed building blocks such as Bang-Bang Phase Detectors, frequency dividers and PRBS generators can be more accurately regulated with the proposed CML approach. The prototype is fabricated to experimentally compare the process-variation-induced performance degradation between the conventional and the proposed CML. Compared to the conventional CML, the proposed architecture significantly reduces the performance degradation on divider self-oscillation frequency, PRBS generator speed and PRBS output jitters over the process-variation with only

Available in PDF, EPUB and Kindle. Book excerpt: While being frequency compact and easy to implement, Non-Return to Zero (NRZ) encoded data does not contain any energy at its clock frequency which makes the clock extraction impossible using any kind of Linear Time Invariant (LTI) operations. Therefore, Clock Data Recovery circuits (CDRs) have an inherent non linear recovery process. In this work we present a frequency domain analysis of the mechanisms leading to the energy generation at clock frequency for NRZ clock data recovery systems. We also propose a frequency domain analysis which is applicable to both Bang-Bang and linear loops. We show the theory results match the measurements very well.

This book was released on 2017-01-12 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: This IBM® RedpaperTM publication describes the adapter-based virtualization capabilities that are being deployed in high-end IBM POWER7+TM processor-based servers. Peripheral Component Interconnect Express (PCIe) single root I/O virtualization (SR-IOV) is a virtualization technology on IBM Power Systems servers. SR-IOV allows multiple logical partitions (LPARs) to share a PCIe adapter with little or no run time involvement of a hypervisor or other virtualization intermediary. SR-IOV does not replace the existing virtualization capabilities that are offered as part of the IBM PowerVM® offerings. Rather, SR-IOV compliments them with additional capabilities. This paper describes many aspects of the SR-IOV technology, including: A comparison of SR-IOV with standard virtualization technology Overall benefits of SR-IOV Architectural overview of SR-IOV Planning requirements SR-IOV deployment models that use standard I/O virtualization Configuring the adapter for dedicated or shared modes Tips for maintaining and troubleshooting your system Scenarios for configuring your system This paper is directed to clients, IBM Business Partners, and system administrators who are involved with planning, deploying, configuring, and maintaining key virtualization technologies.

Available in PDF, EPUB and Kindle. Book excerpt: The superabundance of data that is created by today's businesses is making storage a strategic investment priority for companies of all sizes. As storage takes precedence, the following major initiatives emerge: Flatten and converge your network: IBM® takes an open, standards-based approach to implement the latest advances in the flat, converged data center network designs of today. IBM Storage solutions enable clients to deploy a high-speed, low-latency Unified Fabric Architecture. Optimize and automate virtualization: Advanced virtualization awareness reduces the cost and complexity of deploying physical and virtual data center infrastructure. Simplify management: IBM data center networks are easy to deploy, maintain, scale, and virtualize, delivering the foundation of consolidated operations for dynamic infrastructure management. Storage is no longer an afterthought. Too much is at stake. Companies are searching for more ways to efficiently manage expanding volumes of data, and to make that data accessible throughout the enterprise. This demand is propelling the move of storage into the network. Also, the increasing complexity of managing large numbers of storage devices and vast amounts of data is driving greater business value into software and services. With current estimates of the amount of data to be managed and made available increasing at 60% each year, this outlook is where a storage area network (SAN) enters the arena. SANs are the leading storage infrastructure for the global economy of today. SANs offer simplified storage management, scalability, flexibility, and availability; and improved data access, movement, and backup. Welcome to the cognitive era. The smarter data center with the improved economics of IT can be achieved by connecting servers and storage with a high-speed and intelligent network fabric. A smarter data center that hosts IBM Storage solutions can provide an environment that is smarter, faster, greener, open, and easy to manage. This IBM® Redbooks® publication provides an introduction to SAN and Ethernet networking, and how these networks help to achieve a smarter data center. This book is intended for people who are not very familiar with IT, or who are just starting out in the IT world.
