Up to two frequency select pins are available on the Si5350C. Each of the frequency select pins can be linked to
any of the clock outputs as shown in Figure 8. For example, FS_0 can be linked to control clock frequency
selection on CLK0, CLK3, and CLK5; FS_1 can be used to control clock frequency selection on CLK1, CLK2, and
CLK4. Any other combination is also possible.
The Si5350C uses control circuitry to ensure that frequency changes are glitchless. This ensures that the clock
always completes its last cycle before starting a new clock cycle of a different frequency.

4.4.3. Output Enable (OEB_0, OEB_1, OEB_2)
Up to three output enable pins (OEB_0/1/2) are available on the Si5350C. Similar to the FS pins, each OEB pin
can be linked to any of the output clocks. In the example shown in Figure 9, OEB_0 is linked to control CLK0,
CLK3, and CLK5; OEB_1 is linked to control CLK6 and CLK7, and OEB_2 is linked to control CLK1, CLK2, CLK4,
and CLK5. Any other combination is also possible. If more than one OEB pin is linked to the same CLK output, the
pin forcing a disable state will be dominant. Clock outputs are enabled when the OEB pin is held low.
The output enable control circuitry ensures glitchless operation by starting the output clock cycle on the first leading
edge after OEB is asserted (OEB = low). When OEB is released (OEB = high), the clock is allowed to complete its
full clock cycle before going into a disabled state. This is shown in Figure 9. When disabled, the output state is
configurable as disabled high, disabled low, or disabled in high-impedance.
