DESCRIPTION
The PLL500-17B/27B/37B are a low cost, high per-
formance, low phase noise, and high linearity VCXO
family for the 17 to 130MHz range, providing less
than -130dBc at 10kHz offset. The very low jitter (2.5
ps RMS period jitter) makes these chips ideal for
applications requiring voltage controlled frequency
sources. The IC’s are designed to accept fundamen-
tal resonant mode crystals.

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.
