a high speed Serial Digital Interface video signal jitter measurement method
Journal of Physics: Conference Series, 2019Co-Authors: He Chen, Hongying Gao, Kejia ZhaoAbstract:This paper designs a measurement method for high-speed Serial Digital Interface video signal jitter. Firstly, we introduce the features of SDI signal and the jitter measurement methods of traditional high-speed Serial signals. A jitter model is built for the SDI signal while the properties of the components are analysed. An adjusted dual-Dirac model is adopted to measure the jitter in the signal. This method can accurately analyse different jitter components in SDI signals. It is directly performed on oscilloscope, which is beneficial to the traceability of the jitter. The feasibility of the method is verified by experiments. The measurement results show that the method has better measurement accuracy than the direct spectrum method.

Serial Digital Interface video signal jitter generator and its calibration method
Measurement, 2017Co-Authors: He Chen, Zhijun Yang, Di TianAbstract:Abstract Jitter is an important factor for Serial Digital Interface video signal (SDI signal) analysis. In this paper, we present the simulated SDI signal generator with certain amount of jitter using a sinusoidal frequency modulation (FM) signal, and propose a calibration method for the jitter value based on modulation index and relative power of sinusoidal FM signal. An experimental system is set up to generate and calibrate SDI signal with specific jitters. High-definition (HD) SDI signal with bit rate of 1.485 Gbit/s is employed to describe the calibration procedure and analyze the uncertainty of measurement.

Design and Compliance Testing of a SiGe WCDMA Receiver IC With Integrated Analog Baseband
Proceedings of the IEEE, 2005Co-Authors: Scott K. Reynolds, Brian Floyd, Troy J. Beukema, Thomas Zwick, Ullrich R. PfeifferAbstract:A 2.7-3.3 V 32-mA SiGe direct-conversion wide-band code division multiple access (WCDMA) receiver IC integrating the RF front-end and analog baseband on a single chip has been completed and measured. Analog performance specifications for the design were driven by the 3GPP specifications. To close the loop from 3GPP specifications to IC design specifications to hardware performance results, a subset of compliance tests for both the analog as well as the Digital 3GPP specifications was performed. The IC design includes a bypassable low-noise amplifier (LNA), a quadrature direct-downconverter, an automatically tuned channel-select filter, wide dynamic-range baseband amplifiers, and a Serial Digital Interface. Power-saving modes allow the LNA to be powered down when the input signal is sufficiently large, reducing current consumption to 23 mA. In addition, the entire Q-channel signal path can be optionally powered down during control-channel monitoring, further reducing current draw to 17 mA nominal. The IC showed full compliance with the static channel 3GPP specification tests performed, including all analog/RF compliance tests and a set of DPCH/spl I.bar/Ec/Ior sensitivity tests from 12.2 through 384 kb/s as measured with a software baseband processor.
