External Peripheral Interfaces
The following sections provide information on external peripheral interfaces.
Table 63. DDR2 SDRAM Read Cycle1
1 Test conditions are: Capacitance of 15 pF for DDR contacts. The recommended drive strength is Medium for SDCLK and High
for address and controls

SDCLK = 200 MHz2
2 SDCLK and DQS related parameters are being measured from the 50% point. that is, high is defined as 50% of signal value
and low is defined as 50% as signal value. DDR SDRAM CLK parameters are measured at the crossing point of SDCLK and
SDCLK_B.
