(1) Unless functionally limited to a smaller range in the ADC12DJ5200RF Operating Modes  table based on programmed JMODE.
(2) This parameter only applies to JMODE settings that use 8B/10B encoding or settings that use 64B/66B encoding and 4x or 8x decimation. SYNC is not used for 64B/66B encoding modes unless the DDC block and NCOs are used and require synchronization.
(3) Use SYSREF_POS to select an optimal SYSREF_SEL value for the SYSREF capture, see the SYSREF Position Detector and Sampling Position Selection (SYSREF Windowing) section for more information on SYSREF windowing. The invalid region, specified by tINV(SYSREF), indicates the portion of the CLK± period(tCLK), 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±.
(4) It is recommended to use SYSREF_ZOOM = 0 below fCLK = 3GHz and SYSREF_ZOOM = 1 above fCLK = 3GHz
