RESET AC Electrical Characteristics
This section describes the AC electrical specifications for the reset initialization timing requirements of
the device. Table 10 provides the reset initialization AC timing specifications for the DDR SDRAM
component(s).

Notes:
1. This table applies for pins PORESET, HRESET, SRESET, and QUIESCE.
2. HRESET and SRESET are open drain pins, thus VOH is not relevant for those pins.

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 CLKIN input, and PCI_SYNC_IN period depends on the value of CFG_CLKIN_DIV. See the
MPC8360E PowerQUICC II Pro Integrated Communications Processor Family Reference Manual for more details.
2. tCLKIN is the clock period of the input clock applied to CLKIN. It is only valid when the device is in PCI host mode. See the
MPC8360E PowerQUICC II Pro Integrated Communications Processor Family Reference Manual for more details.
3. POR config signals consists of CFG_RESET_SOURCE[0:2] and CFG_CLKIN_DIV.
