FREQUENCY SELECTION TABLE
The following table provides the necessary information for setting the control lines for proper operation of the
SM532 and for any frequency within its operating range. Note that the table includes operating frequencies at 3.3
and 5.0 VDC. The 3.3 VDC columns are lower in frequency than the 5.0 VDC operation due to the characteristics
of the VCO.
