1. When using an external clock input, the XTI duty should be 50% with 3.3V clock signal amplitude level. The input signal voltage should not exceed the
absolute maximum rating, otherwise damage may occur.
2. The numeric values are measured values obtained using the circuit in Figure 1 and the NPC standard evaluation board.
3. The numeric values are measured values obtained using the circuit in Figure 2 and the NPC standard evaluation board.
4. This is the time, after the supply is turned ON from the OFF state, until the output clock reaches ± 0.1% of the specified frequency.
