DDR and DDR2 SDRAM
This section describes the DC and AC electrical specifications for the DDR SDRAM interface. Note that
DDR SDRAM is GVDD(typ) = 2.5 V and DDR2 SDRAM is GVDD(typ) = 1.8 V.

Notes:
1. tPCI_SYNC_IN is the clock period of the input clock applied to PCI_SYNC_IN. When the device is In PCI host mode the
primary clock is applied to the SYS_CLK_IN input, and PCI_SYNC_IN period depends on the value of CFG_CLKIN_DIV.
2. tSYS_CLK_IN is the clock period of the input clock applied to SYS_CLK_IN. It is only valid when the device is in PCI host mode.
3. POR configuration signals consists of CFG_RESET_SOURCE[0:2] and CFG_CLKIN_DIV.
