Timing
Featured Timing Software and Tools
ClockBuilder Pro Software
Create a customized configuration and part number, interfaces to all evaluation boards and field programmers at no cost.
PCIe Clock Jitter Tool
Quickly and easily take jitter measurements for PCIe Gen1/2/3/4/5 and SRIS/SRNS at no cost.
Phase Noise to Jitter Calculator
Convert phase noise to phase jitter, period jitter, and cycle-to-cycle jitter.
Oscillator Phase Noise Look-up Tool
Quickly lookup phase noise plots for the specific oscillator part number and output frequency.
AccuTime IEEE 1588 Software
Field-proven IEEE 1588 software used by Silicon Labs network synchronizers and module applications.
Customize Clock Generators Using ClockBuilder Pro
Speeds Up Clock Tree Design
ClockBuilder Pro (CBPro) is designed to simplify clock tree design and device configuration. This software uses an easy-to-operate user interface that can customize Silicon Labs’ Clock Generators and Jitter Attenuators, request a custom part number and request custom phase noise plot reports. CBPro connects to all related EVBs and the CBPro Field Programmer that can then be used to program devices already mounted on customer boards. Release notes, CLI (Command Line Interface) documentation and general training information are also included in the software package.
Isolation
