Abracon Holdings, LLC. (Abracon), a leading global manufacturer of passive & electromechanical timing, synchronization, power, connectivity and RF components has held the industry’s best kept secret: the simplest web-based calculator for intuitive and easy conversion of phase noise to rms phase jitter.
Oscillators for high performance applications such as communications, test and measurement, high performance computing (HPC) and RF systems typically specify single-sided phase noise but may not specify jitter or may not specify over the appropriate integration band. Additionally, some suppliers such as FPGA manufacturers provide phase noise requirements in the form of masks instead of an integrated output jitter requirement. Calculating phase jitter from phase noise becomes necessary when comparing clocks and oscillators for a given application. Abracon’s Phase Noise to Jitter Calculator was designed as an interactive tool that easily bridges the gap between phase noise and jitter. To use the calculator, enter the carrier frequency, integration start and stop offsets, phase offset and phase noise in dB/Hz for a given number of points. The calculator outputs total integrated phase jitter over a specified integration band. A key feature, the integration band is user defined allowing multiple integration bands of interest to be compared.
“Engineers often work with phase noise masks and phase noise requirements instead of phase jitter. They are forced to calculate jitter using spreadsheets or math CAD software,” explains Syed Raza, Abracon’s VP of Engineering. “Our calculator has enabled engineers to interactively manipulate phase noise points and immediately evaluate the integrated phase jitter.”
“As the supplier of industry leading ultra-low phase noise and ultra-low jitter oscillator products,” says Juan Conchas, Abracon’s Director of Marketing, “we saw the need to quickly translate phase noise into phase jitter enabling a simple solution for our FPGA and other high performance customers.”
The calculator also features pre-loaded phase noise profiles of existing oscillators operating at various carrier frequencies. For instance, selecting the AOCJY7TQ-100.000MHz shows an impressive 20fs of output jitter over 12kHz to 20MHz band and an amazing 4.5fs over 1kHz to 1MHz band. To save and compare results, you can export your phase noise plot and output jitter data into a PDF download.
Abracon’s phase noise to jitter calculator has received popular reviews from students and professionals in the field. The company expects to roll out additional features and updates in 2017.
