Timing was designed for a system load between 5pF and 20pF
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_M_CLK
Output valid for DDRI_DQS prior to each edge of
DDRI_M_CLK.
DDRI_DQS output hold time after each edge of
the DDRI_M_CLK.
Output valid for ADDR/CTRL prior to the rising
edge of 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.
ETH_MDIO, clock to output timing with respect to
rising edge of ETH_MDC clock
ETH_MDIO output hold timing after the rising
edge of ETH_MDC clock
ETH_MDIO input setup prior to rising edge of
ETH_MDC clock
ETH_MDIO hold time after the rising edge of
ETH_MDC clock
