Pin Description
Glitch-Free Output Frequency Transitions
Customarily when zero delay buffers have their internal
counters change “on the fly” their output clock periods will:
1. Contain short or “runt” clock periods. These are clock cycles
2. Contain stretched clock periods. These are clock cycles in
35,39
45,49
43,47,51
1
in which the cycle(s) are shorter in period than either the
old or new frequency that is being transitioned to.
which the cycle(s) are longer in period than either the old
or new frequency that is being transitioned to.

Common ground for Qc(0:3) output bank and VCO_sel pin.
Analog Ground
This device specifically includes logic to guarantee that runt
and stretched clock pulses do not occur if the device logic
levels of any or all of the following pins changed “on the fly”
while it is operating: Fsela, Fselb, Fselc, and VCO_Sel
