NOTES:
Symbol
1. DDRI_M_CLK is representative of all DDRI_CK and DDRI_CK_N signals. The rising edge of
DDRI_M_CLK
DDRI_M_CLK represents the crossover point of the respective DDRI_CK and DDRI_CK_N signals. The
skew between the separate DDR clocks have been compensated in the timings which have been
described. The period to period clock jitter on each DDRI_M_CLK pair is spec’ed at +/-100ps.
