(1) This parameter is measured with the LMH1297EVM (Evaluation board for LMH1297).

(2) This limit is ensured by bench characterization and is not production tested.

(3) V_OVERSHOOT overshoot/undershoot maximum measurements are largely affected by the PCB layout and input test pattern. The maximum value specified in Section 7.5 for V_OVERSHOOT is based on bench evaluation across temperature and supply voltages with the LMH1297EVM.
