PLL and Jitter Spectrum Analysis using the 86100C Digital Communications Analyzer

Detection and Evaluation of Deterministic Jitter Causes in CP-PLL's Due to Macro Level Faults and Pre-Detection Using Simple Methods

Charge-Pump Phase-locked loops are currently used in a variety of signal generation applications. Due to the usefulness of the device CP-PLLs are now commonplace inclusions in SOC designs, and ultimately determine performance of other SOC blocks, such as ADC’s, DAC’s, RF functions and fibre communications channels. In many situations, only simple frequency lock tests are carried out on the PLL ...

A new pattern jitter free frequency error detector

One method to enable fast acquisition of a phase-locked loop (PLL) in spite of large frequency offsets and small PLL bandwidths is to use an additional AFC loop. A suitable frequency error detector (FED) for large frequency offsets is the well-known balanced quadricorrelator. This FED is shown to produce great pattern jitter if it is to work with digital modulated MQAM and MPSK signals (M > 2) ...

Frequency Tracking Performance Using a Hyperbolic Digital-Phase Locked Loop for Ka-Band Communication in Rain Fading Channels

In this paper we study and present some results on the performances of frequency tracking for Ka-band satellite communications in rain fading channels. The carrier frequency is tracked using a 2 order hyperbolic phase detector based digital-phase locked loop (D-PLL). The hyperbolic D-PLL has the capability of extending the tracking range compared to the other D-PLL and hence can be designed suc...

Extraction of Instantaneous and RMS Sinusoidal Jitter Using an Analytic Signal Method

This paper describes a new method for extracting both instantaneous and rms sinusoidal jitter from phase-locked loops (PLL) output signals. The method is based on analytic signal theory and utilizes the Hilbert transform to extract phase information from a PLL signal. Both the theoretical basis and fundamental concepts of the new method are explained. A unified review of conventional methods is...
