(1) For subgroup definitions, please see Table 6-1.

(2) Unless functionally limited to a smaller range in Table 7-18 based on the programmed JMODE.

(3) Use SYSREF_POS to select an optimal SYSREF_SEL value for SYSREF capture, see SYSREF Position Detector and Sampling Position Selection (SYSREF Windowing) for more information on SYSREF windowing. The invalid region, specified by t_INV(SYSREF), indicates the portion of the CLK± period (t_CLK), as measured by SYSREF_SEL, that may result in a setup and hold violation. Verify that the timing skew between SYSREF± and CLK± over system operating conditions from the nominal conditions (that used to find optimal SYSREF_SEL) does not result in the invalid region occurring at the selected SYSREF_SEL position in SYSREF_POS, otherwise a temperature dependent SYSREF_SEL selection may be needed to track the skew between CLK± and SYSREF±.
