Notas de aplicación
- AN-1865 Frequency Synthesis and Planning for PLL Architectures (Rev. C)PDF, 173 Kb, Revisión: C, Archivo publicado: abr 26, 2013
This application report demonstrates the importance of understanding the least common multiple (LCM) and greatest common divisor (GCD). - AN-1821 CPRI Repeater System (Rev. A)PDF, 1.2 Mb, Revisión: A, Archivo publicado: abr 26, 2013
This application report implements the Common Public Radio Interface (CPRI) for Remote Radio Heads(RRHs). The designer can use this application report for developing CPRI-based repeater systems inpoint-to-point or multi-hop configurations. This application report consists of:Designs for the CPRI SerDes Repeater Boards for the Radio Equipment (RE) and Radio EquipmentController (REC) - Phase Synchronization with Multiple Devices and Frequencies (Rev. A)PDF, 199 Kb, Revisión: A, Archivo publicado: abr 26, 2013
This application note discusses how phase synchronization can be achieved when multiple chips are involved and also when the frequencies are not the same. - AN-1910 LMK04000 Family Phase Noise Characterization (Rev. A)PDF, 5.1 Mb, Revisión: A, Archivo publicado: abr 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, Revisión: A, Archivo publicado: abr 26, 2013
This application report for the LMK04000 family of clock conditioners covers the design of an external oscillator circuit using a crystal resonator. - AN-1734 Using the LMK03000C to Clean Recovered Clocks (Rev. B)PDF, 193 Kb, Revisión: B, Archivo publicado: abr 26, 2013
This application note delivers an example of how to clean recovered clocks, using the SCAN25100 SERDES and LMK03000C clock conditioner.
