*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.
