Response time from power on (or applying the clock to XT1) to SCKO settling time is typically 3 ms. Delay time from
sampling frequency change to SCKO settling is 300 ns maximum. Figure 10 illustrates SCKO transient timing in the
PLL1708.

Figure 10. System Clock Transient Timing
The delay time for hardware control to use SR, FS2, FS1, or CSEL is 150 ns maximum. Figure 11 illustrates SCKO transient
timing in the PLL1707. Clock transient timing is not synchronized with the SCKOs. External buffers are recommended on
all output clocks in order to avoid degrading the jitter performance of the PLL1707/8.
