Data Sheet
I/O Timing—DDR SDRAM TDS
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).

I/O Timing—DDR SDRAM TSK, TSA, and THA
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).
