440GP – Power PC 440GP Embedded Processor  
Data Sheet  
I/O Timing—DDR SDRAM T  
DS  
Notes:  
1. All of the DQS signals are referenced to MemClkOut0(0).  
2. The TDS values in the table include 3/4 of a cycle at the indicated clock speed.  
3. To obtain adjusted values for lower clock frequencies, subtract 5.625 ns from the values in the table and add 3/4 of the cycle  
time for the lower clock frequency (TDS - 5.625 + 0.75TCYC).

Notes:  
1. TSK is referenced to MemClkOut0(0). TSA and THA are referenced to MemClkOut0(90).  
2. To obtain adjusted TSA values for lower clock frequencies, use 3/4 of the cycle time for the lower clock frequency and  
subtract TSK maximum (0.75TCYC - TSKmax).  
3. To obtain adjusted THA values for lower clock frequencies, use 1/4 of the cycle time for the lower clock frequency and add  
TSK minimum (0.25TCYC + TSKmin).
