The Impact of Power Rail Noise on Clock Jitter

Noise on the power rail may not only create bit errors due to voltage spikes, but it may also increase clock jitter. Clock jitter is an insidious source of noise difficult to debug.
In this webinar, we demonstrate how to measure the jitter in both clocks and data and identify the contribution from noise on the power rail. These techniques can be applied to any system in which minimizing clock and data jitter is important.
Topics to be covered in this webinar:

  • Using time interval error (TIE) to measure jitter
  • The statistics and spectrum of TIE as a way of characterizing jitter
  • Typical jitter in various types of oscillator circuits
  • Best practices to measure power rail noise
  • The impact power noise can have on clock jitter
  • Examples of clocked systems with high and low jitter sensitivity to power rail noise

Who should attend? Hardware and circuit engineers who design interconnects and clocked circuits.

What attendees will learn? This webinar will introduce you to how to measure jitter and power rail noise, and how to reduce the sensitivity of your clocks to power rail noise.

Presenter: Dr. Eric Bogatin, Teledyne LeCroy Fellow, Teledyne LeCroy

The workhorse instrument used to characterize all PCB traces is the Time Domain Reflectometer (TDR). But its measurements are often mis-interpreted because the impedance properties of transmission lines are confusing.
Join Eric Bogatin and Teledyne LeCroy for this webinar that will show you the right way to think about signals on transmission lines and how to interpret TDR results. Using live measurements, we’ll look at some cool examples of the properties of real circuit board traces.
Topics to be covered in this webinar:

  • What is characteristic and instantaneous impedance?
  • How a TDR measures instantaneous impedance
  • How to read the characteristic impedance off the front screen of a TDR
  • How to interpret discontinuities
  • The limitations to a single channel TDR

Who should attend? Any engineer who uses a TDR or uses TDR measurements.

What attendees will learn? How to get the most value from TDR measurements to analyze your interconnects.

Presenter: Dr. Eric Bogatin, Teledyne LeCroy Fellow, Teledyne LeCroy
