Multiplicator
The m u ltiplier applied to the inpu t frequ ency. The possible valu es are:

Frequ ency is m u ltiplied by 256 (PLC_rsI0_Mu ltiplier = Frequ encyX256)

Frequ ency is m u ltiplied by 16 (PLC_rsI0_Mu ltiplier = Frequ encyX16)

Frequ ency is m u ltiplied by 4096 (PLC_rsI0_Mu ltiplier = Frequ encyX4096)
Divider
The d ivid er ap plied to the inpu t frequ ency. The resu lting frequ ency is com pu ted as follow s:
output _ frequency
Input Selection
Ind icates w hich label in the GPIO LUT w ill be associated w ith the rescaler. Make su re you select an inpu t label
that is not being u sed for its d efau lt behavior. For exam ple, Q9 is u sed to send a trigger to pu lse generator 0. If
pu lse generator 0 is u sed in triggered m od e, then it w ill be triggered by Q9 and cannot be u sed as the inpu t for
the rescaler. The possible valu es are: Q3, Q7, Q8. Q9, Q10, Q11, Q16, and Q17.
Backup Enabled
Ind icates if the rescaler w ill u se a back-u p inpu t sou rce if its m ain sou rce stop s its activity.
Backup Window
Specifies the w ind ow of tim e d u ring w hich there can be n o activity from the m ain inp u t sou rce before the
rescaler sw itches to the back-u p sou rce. As soon as activity is d etected , the rescaler retu rns to its m ain inpu t
sou rce.
Backup Input
Sam e as the m ain inpu t sou rce
Granularity
Ind icates the nu m ber of PCI clock cycles that are u sed for each increm ent of the d elay and w id th. The am ou nt
specified in the granu larity is m u ltiplied by 30 nanosecond s.
Other Rescaler equ ations are:

Granu larity_setting = [1, 4, 16, 256]

Mu ltiplier_setting = [16, 256, 4096]

Divid er_setting [15:0] = [0..65535]

Granu larity = 30ns x Granu larity_setting

sig_in_period _cou nter [15:0] = MIN ( IN T( Signal_In_Period / Granu larity ), 65535)

m u ltiplier_ou t [31:0] = sig_in_period _cou nter[15:0] x Mu ltiplier_setting[15:0]

d ivid er_ou t[27:0] = IN T ( m u ltiplier_ou t[31:0] / Divid er_setting )

Signal_Ou t_Period = MAX( d ivid er_ou t[27:0], 2 ) x Granu larity
