DIFFERENTIAL LVPECL FREQUENCY SYNTHESIZER
If the FREF_EXT input is driven by a 3.3V LVCMOS driver, the
jitter performance can be improved by reducing the amplitude
swing and slowing down the edge rate.
Figure 7A shows an
amplitude reduction approach for a long trace. The swing will
be approximately 0.85V for logic low and 2.5V for logic high

JITTER REDUCTION FOR FREF_EXT SINGLE END INPUT
(instead of 0V to 3.3V).
Figure 7B shows amplitude reduction
approach for a short trace. The circuit shown in
Figure 7C
reduces amplitude swing and also slows down the edge rate
by increasing the resistor value.
