Book excerpt: Baud-rate clock recovery (CR) is gradually gaining popularity in modern serial data transmission systems since these CR techniques do not require edge-samples for extracting timing information. However, previous baud-rate techniques for high-speed serial links either rely on specific 4-bit patterns or uncorrelated random data. This work describes the modeling and design of analog filter front-end aided baud-rate CR schemes. Unlike other baud-rate schemes, this technique is not constrained by the properties of the input random data.Firstly, the thesis develops a hardware-efficient baud-rate algorithm that requires only the slope information of the incoming random data. Called modified sign-sign minimum mean squared error (SSMMSE), this algorithm adjusts the clock sampling phase until the slope is zero through a bang-bang control loop. Secondly, the performance of a modified SSMMSE phase detector is investigated and compared with a conventional edge-sampled phase detector. It is shown that, at severe noise levels, the proposed modified SSMMSE method has better performance compared to the edge-sampled method for equal loop bandwidths. Thirdly, the thesis investigates different hardware-efficient slope detection techniques. Both passive and active filter based slope detection techniques are demonstrated in this work. In addition to slope generation, the active filter performs linear equalization as well. However, the passive filter generates the slope information at higher speeds than the active filter and also consumes less power. The two filters are used to recover a 2-GHz clock by using an external bang-bang loop. In short, the thesis demonstrates that area and power savings can be achieved by utilizing slope information from front-end filters without compromising the performance of the CR unit.

Download or read book High Speed Baud Rate Clock and Data Recovery written by Danny Yoo and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents an adaptive baud-rate CDR with CTLE and 1-tap DFE. The novelty in this design is the adaptation engine tailored for baud-rate clock and data recovery where the comparators for the DFE and the PD are shared to save power. A testchip was fabricated in TSMC 28nm CMOS. The adaptation engine is demonstrated for 34-36Gb/s operation with a Tyco 5" channel resulting in 15.05-18.25dB channel losses. At 35Gb/s, the total power consumption is measured to be 106.3mW or a FOM of 3.04pJ/bit. This thesis also presents a 2x half-baud-rate clock and data recovery technique with 2x oversampling at half-baud-rate (every other UI). A testchip was also fabricated in TSMC 28nm CMOS. A 30Gb/s 2x half-baud-rate CDR was tested with a Tyco 5" channel with 13.06dB of loss. The total power consumption is measured to be 79.2mW or a FOM of 2.64pJ/bit.

Available in PDF, EPUB and Kindle. Book excerpt: Baud rate clock and data recovery circuits are critical to high speed serial links since these require only one sample per data period thereby requiring low speed samplers and comparators. This work models and discusses the backend of one particular Baud rate CDR – Mueller Muller, and analyses some of the building blocks of the CDR – Phase Detector, Phase Interpolator and the Quadrature Phase Generator. Firstly, a PAM-4 Quadrature Phase Detector operating at 80Gb/s is discussed. The challenges associated with designing a Mueller-Muller PD for an asymmetric channel are discussed and one way to resolve this issue is proposed. Then the underlying digital blocks that make up the Phase detector are expanded upon. Secondly, a 64-step digitally controlled Phase Interpolator running at 16GHz clock rate is analyzed and its design challenges with regards to achieving linearity and ensuring duty cycle fidelity are explored. Finally, a Quadrature Phase Generator with digital delay control is analyzed. It is modeled at 16GHz clock rate and the range/resolution problem and its impact on clock jitter is explored.

This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents the analysis, design, simulation, and measurements of a frequency detection method for a reference-less baud-rate clock data recovery (CDR) circuit. This CDR was designed with a continuous-time linear equalizer (CTLE) and a 1-tap decision feedback equalizer (DFE) to implement a high-speed wireline receiver in a 28nm CMOS process and packaged in a 40-pin Quad-Flat No-leads (QFN) package. The frequency detection method automatically controls an adjustable baud-rate phase detector to correct frequency error between the incoming data and the recovered clock without a separate frequency acquisition loop in the CDR. To characterize the performance of this method, PRBS-31 data ranging from 22.5Gb/s to 32Gb/s was transmitted across a Tyco 5-inch channel with -10.1dB to -14.8dB channel loss at Nyquist. The frequency detection method was measured to achieve a capture range of 34%. The entire receiver achieved a power eciency ranging from 2.9pJ/bit to 3.2pJ/bit.

This book was released on 2008-12-19 with total page 495 pages. Available in PDF, EPUB and Kindle. Book excerpt: The simplest method of transferring data through the inputs or outputs of a silicon chip is to directly connect each bit of the datapath from one chip to the next chip. Once upon a time this was an acceptable approach. However, one aspect (and perhaps the only aspect) of chip design which has not changed during the career of the authors is Moore’s Law, which has dictated substantial increases in the number of circuits that can be manufactured on a chip. The pin densities of chip packaging technologies have not increased at the same pace as has silicon density, and this has led to a prevalence of High Speed Serdes (HSS) devices as an inherent part of almost any chip design. HSS devices are the dominant form of input/output for many (if not most) high-integration chips, moving serial data between chips at speeds up to 10 Gbps and beyond. Chip designers with a background in digital logic design tend to view HSS devices as simply complex digital input/output cells. This view ignores the complexity associated with serially moving billions of bits of data per second. At these data rates, the assumptions associated with digital signals break down and analog factors demand consideration. The chip designer who oversimplifies the problem does so at his or her own peril.
