Notes to Table 1–62:
(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 DDIO circuits clocked by a PLL output routed on a global
clock network.
(3) The memory output clock jitter stated in Table 1–62 is applicable when an input jitter of 30 ps is applied.
