DDR2 and DDR3 SDRAM Differential Timing Specifications
This section describes the DC and AC differential electrical specifications for the DDR2 and DDR3
SDRAM controller interface of the MPC8572E.
NOTE
VID specifies the input differential voltage |VTR -VCP| required for
switching, where VTR is the true input signal (such as MCK or MDQS) and
VCP is the complementary input signal (such as MCK or MDQS).
Table 18 provides the differential specifications for the MPC8572E differential signals MDQS/MDQS and
MCK/MCK when in DDR2 mode.
