Notes to Table 1–49:
(1) The memory output clock jitter measurements are for 200 consecutive clock cycles, as specified in the JEDEC DDR2/DDR3 SDRAM standard.
(2) The clock jitter specification applies to memory output clock pins generated using differential signal-splitter and DDIO circuits clocked by a PLL
output routed on a regional or global clock network as specified. Altera recommends using regional clock networks whenever possible.
(3) The memory output clock jitter stated in Table 1–49 is applicable when an input jitter of 30 ps is applied.
(4) The clock jitter specification is characterized with 70% utilization, 266 MHz core clock frequency, and 12.5% design toggle rate. If your design
exceeds any of these conditions, the jitter specification of the design may not meet the above specification.
