2.2 Wander Generation TDEV G.8262 EEC Option 1

While the DPLL is locked to an input clock signal that is wander-free, it will not generate wander that exceeds the green TDEV mask shown in Figure 2-4 (Figure 2 in the G.8262 specification). The LMK5C33216 passed the Wander Generation TDEV G.8262 EEC Option 1 requirement as shown in Figure 2-4.
