PLL Analysis Tool
Applications of the PLL Analysis Tool
• Find the transfer function of a 2nd-order PLL
• View the Bode plot of a PLL.
• Identify poles and zero of a 2nd-order PLL.
• Determine PLL characteristics such as lock in damping factor, natural frequency, lock range, lock-in time,
pull-in time, pull-out range, etc.
Overview
The PLL Analysis tool permits users to study characteristics and parameters of a 2nd-order PLL. With a
simple set of variance measurements, the tool can extract information such as damping factor, natural
frequency, input noise level, lock range, lock-in time, pull-in time, pull-out range and noise bandwidth.
The tool also presents a transfer function and Bode plots up to the natural frequency, as well as a plot of
the poles and zero for a 2nd-order PLL.
