(1) Prolonged use above a junction temperature of 105°C may increase the device failure-in-time (FIT) rate.
(2) Measured to AGND.
(3) Measured to DGND.
(4) TI strongly recommends that CLK± be AC-coupled with DEVCLK_LVPECL_EN set to 0 to allow CLK± to self bias to the optimal input common-mode voltage for best performance. TI recommends AC-coupling for SYSREF± unless DC-coupling is required, in which case LVPECL input mode must be used (SYSREF_LVPECL_EN = 1).
(5) TMSTP± does not have internal biasing, which requires TMSTP± to be biased externally whether AC-coupled with TMSTP_LVPECL_EN = 0 or DC-coupled with TMSTP_LVPECL_EN = 1.
(6) ADC output code saturates when VID for INA± or INB± exceeds the programmed full-scale voltage (VFS) set by FS_RANGE_A for INA± or FS_RANGE_B for INB±.
