DDRI_M_CLK
DDRI_M_CLK is representative of all DDRI_CK and DDRI_CK_N signals. The rising edge of
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.
DDRI_DQS
ADDR/CTRL output hold time after the rising
edge of the DDRI_M_CLK. Address and control
signals consist of DDRI_RAS_N, DDRI_CAS_N,
DDRI_CS_N, DDRI_WE_N, DDRI_BA, DDRI_MA,
and DDRI_CKE.
Output valid for DDRI_DQ, DDRI_CB, and
DDRI_DM prior to each edge of DDRI_DQS.
DDRI_DQ, DDRI_CB, and DDRI_DM output hold
time after each edge of the DDRI_DQS.
