4 years agoNeed controller Timing parameters of Cyclone V memory device
Hi Team,
Greetings..!
I am performing the Signal Integrity analysis of Cyclone V (5CSXFC6D6F31C6N) and DDR Interface (DDR3, 800MHz).
Kindly help us in deriving the min and Max values of the Following parameters to complete the analysis.
1. tCKAC - Addr/Cmd prelaunch delay, relative to CK(r) (1T)
2. tCKCTL - ctl prelaunch delay, relative to CK(r)
3. tCKDQS - DQS delay, relative to CK
4. tDQSDQ - DQ prelaunch delay, relative to DQS
5. tDQDQS - Max. tolerable DQ to DQS skew (-,+) (derived from tDS, tDH)
6. tDS - DQ valid to shifted DQS
7. tDH - Shifted DQS to DQ invalid.
looking forward for your response.
Regards,
Prasad Aginiparthi.
