AV9170
Using CLK2 Feedback
Connecting CLK2 to FBIN as shown in Figure 6 will cause all
of the rising edges to be aligned (Figure 8).
Using CLK1 Feedback
With CLK1 connected to FBIN as shown in Figure 7, the
input and CLK1 output will be aligned on the rising edge, but
CLK2 can be either rising or falling (Figure 9).

For CLK2 frequencies 10 - 53 MHz* (-04)
For CLK2 frequencies 2.5 - 13.37 MHz (-05)
*Maximum 33.3 MHz @ 3.3V (-04), 8.33 MHz @ 3.3V (-05)
For CLK1 frequencies 20 - 107 MHz (-04)
For CLK1 frequencies 5 - 26.75 MHz (-05)
Maximum 66.7 MHz @ 3.3V (-04), 16.7 MHz @ 3.3V (-05)
