TIDA-010191 clocking board LMX2615-SP devices show almost the same results since both are identical on the board. Table 4-1 shows the measured phase noise performance of the LMX2615-SP at various clock frequencies in the clock board. Measured phase noise plots are shown in Figure 4-5 through Figure 4-7.
