2.2.3.4. Memory Output Clock Jitter Specifications

Table 128.  Memory Output Clock Jitter Specification for Arria V GZ Devices

The clock jitter specification applies to the memory output clock pins generated using differential signal-splitter and DDIO circuits clocked by a PLL output routed on a PHY, regional, or global clock network as specified. Intel recommends using PHY clock networks whenever possible.

The clock jitter specification applies to the memory output clock pins clocked by an integer PLL.

The memory output clock jitter is applicable when an input jitter of 30 ps peak-to-peak is applied with bit error rate (BER) -12, equivalent to 14 sigma.
