AV9110 Quartz Crystal Selection
When an external quartz crystal will be used as a frequency
reference for the
AV9110
, attention needs to be given to
crystal selection if accurate reference frequency and output
frequency is desired. The
AV9110
uses a Pierce oscillator
design which operates the quartz crystal in parallel-resonant
mode. It requires a quartz crystal cut for parallel-resonant
operation to ensure an accurate frequency of oscillation (a
less expensive series-reso-nant crystal can be used with the
device but it will oscillate approximately 0.1% too fast). The
AV9110-01
has internal crystal load capacitors which result
in a total crystal load capacitance of approximately
12pF±10%.The AV9110-02 does not have internal load
capacitors, but contributes about 3pFload capacitance to the
crystal.
Following is a list of recommended crystal devices for the
AV9110
. They have been tested by the crystal manufacturer
to operate suitably with the AV91xx-series crystal oscillator
de-sign, having load capacitance characteristics that are
compatible with the
AV9110-01
.
