Application Notes
- AN-1950 Silently Powering Low Noise Applications (Rev. A)PDF, 10.5 Mb, Revision: A, File published: Apr 22, 2013
This application report explains how to implement a low noise switch mode power supply solution. Itintroduces the sources of noise and explain how to minimize them. A big factor in noise generation andpropagation is the printed circuit board layout. Important basics are discussed. Circuit measurementtechniques are also explained to guide a design engineer towards a low noise but efficient so - AN-1910 LMK04000 Family Phase Noise Characterization (Rev. A)PDF, 5.1 Mb, Revision: A, File published: Apr 26, 2013
The purpose of this applications report is to present phase noise and jitter measurements representing the clock outputs of the LMK04000 family of Precision Clock Conditioners, when paired with various voltage controlled oscillators (VCXOs). The intent is to illustrate the relationship between clock output phase noise and VCXO phase noise. - AN-1939 Crystal Based Oscillator Design with the LMK04000 Family (Rev. A)PDF, 8.2 Mb, Revision: A, File published: Apr 26, 2013
This application report for the LMK04000 family of clock conditioners covers the design of an external oscillator circuit using a crystal resonator.
