90 This specification is limited by the I/O maximum frequency. The maximum achievable I/O frequency is different for each I/O standard and is dependent on design and system specific factors. Ensure proper timing closure in your design and perform HSPICE/IBIS simulations based on your specific design and system setup to determine the maximum achievable frequency in your system.
91 To achieve 5% duty cycle for fOUT_EXT ≥ 300 MHz, you only can use tx_outclk port from the LVDS SERDES Intel FPGA IP. Refer to the Clocking and PLL User Guide for the detail design guidelines.
92 Not applicable for fabric-feeding I/O PLL.
93 PLL phase shift accuracy is 50 ps with the assumption of fVCO = 1.6 GHz.
94 fREF is fIN/N, specification applies when N = 1.
95 Requirement for DDR/LPDDR protocol and LVDS SERDES applications only.
96 The phase noise numbers in this table are the maximum acceptable phase noise values measured at a carrier frequency of 100 MHz. To calculate the phase noise requirement at any other frequency, use the formula: REFCLK phase noise at f (MHz) = REFCLK phase noise at 100 MHz + (20 × log10 (f/100)).
97 This jitter specification does not include the effect of spread-spectrum clock. The magnitude of jitter deterioration is largely depend on the spread-spectrum clock profile used. Refer to the Clocking and PLL User Guide for the recommended spread-spectrum clock profile.
98 External memory interface clock output jitter specifications use a different measurement method, which are available in the Memory Output clock Jitter Specifications table.
