12. When the device is operated with input clock jitter, this parameter needs to be derated by the actual  
tJIT(duty) of the input clock. (output deratings are relative to the SDRAM input clock.)  
For example, if the measured jitter into a DDR2-667 SDRAM has tJIT(duty) min. = 72ps and  
tJIT(duty) max. = +93ps, then tRPST min.(derated) = tRPST min. + tJIT(duty) min. = 0.4 × tCK(avg) −  
72ps = +928ps and tRPST max.(derated) = tRPST max. + tJIT(duty) max. = 0.6 × tCK(avg) + 93ps =  
+1592ps.  
13. Refer to the Clock Jitter table.
