Fig.17 Oscillator application.
(1a) With 3rd-harmonic quartz.
Crystal load = 8 pF.
(1b) With fundamental quartz.
Crystal load = 20 pF.
(2a) With direct clock.
(2b) With fundamental quartz and restricted drive level. When P
of the internal oscillator
is too high, a resistance R
s
can be placed in series with the oscillator output XTALO.
Note: The decreased crystal amplitude results in a lower drive level but on the other hand
the jitter performance will decrease.
