2.1 Wander Generation MTIE Option 1, G.8262 EEC Option 1

While the DPLL is locked to an input clock that is wander-free, it will not generate wander that exceeds the green MTIE masks shown in Figure 2-2 and Figure 2-3. These masks can be seen in Figure 1 in the G.8262 specification. There is no noise modulation applied to the input for this test. The LMK5C33216 passed the Wander Generation MTIE Option 1, G.8262 EEC Option 1 requirement as shown in Figure 2-2 and Figure 2-3.
