with CLK2 Connected to FBIN

Using CLK2 Feedback

Connecting CLK2 to FBIN as shown in Figure 2 will cause all

of the rising edges to be aligned (Figure 4).

Using CLK1 Feedback

With CLK1 connected to FBIN as shown in Figure 3, the input

and CLK1 output will be aligned on the rising edge, but CLK2

can be either rising or falling (Figure 5). Consult ICS if the

CLK1 frequency is desired to be higher than 107MHz.

For CLK2 frequencies 10 - 53.5 MHz* (-01)

For CLK2 frequencies 2.5 - 13.37 MHz (-02)

*Maximum 33.3 MHz @ 3.3V (-01), 8.33 MHz @ 3.3V (-02)

Figure 2:

For CLK1 frequencies 20 - 107 MHz† (-01)

For CLK1 frequencies 5 - 26.75 MHz (-02)

†Maximum 66.7 MHz @ 3.3V (-01), 16.7 MHz @ 3.3V (-02)
