Clock
Timing test were performed with a 70-pF load to ground.
Input setup prior to rising edge of clock. Inputs
included in this timing are SDM_DQ[31:0] (during
a read operation).
Input hold time after the rising edge of the clock.
Inputs included in this timing are SDM_DQ[31:0]
(during a read operation).
Rising edge of clock-to-signal output. Outputs
included in this timing are SDM_ADDR[12:0],
SDM_BA[1:0], SDM_DQM[3:0], SDM_CKE,
SDM_WE_N, SDM_CS_N[1:0], SDM_CAS_N,
SDM_RAS_N, SDM_DQ[31:0] (during a write
operation).
Signal output hold time after the rising edge of
the clock. Outputs included in this timing are
SDM_DQ[31:0] (during a write operation).
