PPT-Clock jitter tests

222012 Goal monitor clock jitter during ramping BEAM1 clock more than 10 ramps done different CORDE delay ranging from 44ns to 10ns PbPb 2011 delays were 44ns 67ns also blowup applied a slow change of frequency roughly in the middle of the ramp . See References 1 2 and 3 ADCs are available with aperture jitter specifications as low as 60fs rms AD9445 14bits 125 MSPS and AD9446 16bits 100 MSPS Extremely low jitter sampling clocks must therefore be utilized so that the ADC performance is n 52 M z will have a pe riod of 6430 pic sec onds for one c lete cycle Successi ve c cles of a no is free wa ve form will measure exactly 6430 picos ec onds The noise elements that will cause the cloc k pe riod to va ry from 6430 p S are kn own as jitt 5 15 25 35 Jitter Freqiency in MHz RMS Jitter Sensitivity in picoseconds Jitter Measurements Using Phase Locked Loops Z ZQZ Z QQZ Z 587Z Z Q DUT Direct Low Jitter Reference Oscillator Phase Detector Loop Filter Measurement Filter Output at this p ‘.
