PLL WITH EXTERNAL VCO AND BAND-PASS
FILTER FOLLOWED BY CLOCK DISTRIBUTION
An external band-pass filter may be used to try to improve the
phase noise and spurious characteristics of the PLL output. This
option is most appropriate to optimize cost by choosing a less
expensive VCO combined with a moderately priced filter. Note
that the BPF is shown outside of the VCO-to-N divider path,
with the BP filter outputs routed to CLK1. Some power can be
saved by shutting off unused functions, as well as by powering
down any unused clock channels (see the Register Map and
Description section).
