DESCRIPTION
DIVIDER SELECTION LOGIC LEVELS
The PL500-15/16 is a low cost, high performance
and low phase noise VCXO for the 1MHz to 18MHz
range, providing less than -130dBc at 10kHz offset
when using a 35.328MHz crystal. The very low jitter
(2.5 ps RMS period jitter) makes this chip ideal for
applications requiring voltage controlled frequency
sources. Input crystal can range from 16MHz to
36MHz (fundamental resonant mode).

Note: The crystal must be such that it oscillates (parallel resonant) at nominal frequency when presented a C Load as specified above.
If the crystal requires more load to be at nominal frequency, the additional load must be added externally. This however may reduce the pull range.
Note that the Cload values above are for the IC only, and do not include PCB parasitics. Crystal specifications for Cload include PC B parasitics.
