All timing is measured at 30 pF loading with the exception of fast I/O signals as discussed below. Refer
to the reference manual’s System Control Chapter for details on drive strength settings.
Table 8 provides the maximum loading guidelines that can be tolerated on a memory I/O signal (also
known as Fast I/O) to achieve 133 MHz operation. These critical signals include the SDRAM Clock
(SDCLK), Data Bus signals (D[31:0]), lower order address signals such as A0-A10, MA10, MA11, and
other signals required to meet 133 MHz timing.
The values shown in Table 8 apply over the recommended operating temperature range. Care must be
taken to minimize parasitic capacitance of associated printed circuit board traces.

DPLL Timing Specifications
Parameters of the DPLL are given in Table 11. In this table, Tref is a reference clock period after the
predivider and Tdck is the output double clock period.
