6.5 Phase Discontinuity G.8262 Option 2

For this test, the requirement is that switching between two input clocks of the same frequency but with different phase will not exceed the green MTIE mask shown in Figure 6-8 (Figure 14 and Table 15 in the G.8262 spec).

The LMK5C33216 met this requirement, as shown in Figure 6-8.
