v10 v11 5 5 6 6 In the following, the green signal is the reference CROC Global clock signal (CROC quartz), the yellow signal 7 is either the clock of the front-end board, the L0 or the read_command. Green is the trigger for the clock study, the yellow signal is the trigger when looking at the L0 and the Read Command. The time scale is 2ns. 7 is either the clock of the front-end board, the L0 or the read_command. Green is the trigger for the clock study, the yellow signal is the trigger when looking at the L0 and the Read Command. The time scale is 2ns. The scope remanence is pushed to 1s (clock studies) or infinity (L0 and RdCmd) in order to show clearly the jitter effect. 8 8 9 == Djitter Clock ==9 == Jitter Clock == 10 10 Incoming clock signal taken at the input of the LVDS/unipolar convertor of the board (polarity minus) 11 11 … … 29 29 30 30 31 == Djitter L0 ==31 == Jitter L0 == 32 32 L0 signal at the output of the LVDS/unipolar convertor of the FEB. 33 33 … … 40 40 41 41 42 == Djitter Read Command ==42 == Jitter Read Command == 43 43 44 44 First RdCmd at the output of the Sequencer.
