(1) Prolonged use above the nominal junction temperature can increase the device failure-in-time (FIT) rate.

(2) SYSREF must be applied for the device to initialize; see the SYSREF Signal section for details.

(3) After power-up, always use a hardware reset to reset the device for the first time; see Table 9-1 for details.

(4) Operating 0.5 dB below the maximum-supported amplitude is recommended to accommodate gain mismatch in interleaving ADCs.

(5) At high frequencies, the maximum supported input amplitude reduces; see Figure 7-37 for details.
