9.1.1 Jitter Cleaning The dual-loop PLL architecture of LMK04610 provides the lowest jitter performance over a wide range of output frequencies and phase noise integration bandwidths. The first stage PLL (PLL1) is driven by an external reference clock and uses an external VCXO to provide a ...
The PLL achieves a multiplication range of 1-4096 with less than 1.7% output jitter. Fabricated in 0.13μm CMOS, the area is 0.182 mm{sup}2 and the supply is 1.5 V.关键词: Adaptive bandwidth Analog circuits Clock generation Clock multiplication Frequency synthesis Phase-locked loop (PLL) ...

Supply and substrate noise tend to cause the output clock of PLLs to jitter from their ideal timing. The design of a low jitter PLL has become challenging because of the many design trade-offs between noise and bandwidth. In order to achieve a low jitter PLL design, fully differential signa...
The PLLs internal to the FPGA will help remove high-frequency jitter. Also, jitter on the input clock will be integrated through the PLL. (So square wave jitter looks like a sawtooth, sawtooth looks like a parabolic, etc.) The integration of random jitter is theoretically 0. It can be...
