Product specification
Programmable ripple counter with
oscillator; 3-state
74HC/HCT6323A
Fig.13 Typical setup for a crystal oscillator
operating in the fundamental mode
(1 MHz to 25 MHz).
Above 5 MHz replace R2 by a capacitor of
half the value of C2.
C
at which a crystal is specified (or adjusted)
equals for this application C1 . C2/C1 + C2.

Fig.14 Typical set-up for a crystal oscillator
operating in the third overtone mode without
the use of an inductor.
Applicable for third overtone crystals (lower
damping resistance at the third harmonic
frequency) at typical 50 MHz. For lower
frequencies extra load capacitors must be
supplied, or increase bias resistor.
