It allows the control of the output frequency with an input voltage (VIN), using a low cost crystal. The chip provides a pullable output at a frequency of F XIN x 16. This makes the PLL502-14 ideal for a wide range of applications.

It is assumed that the crystal will be at nominal frequency at this load. 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. 3. Voltage Control Crystal Oscillator PARAMETERS VCXO Stabilization Time * SYMBOL T VCXOSTB CONDITIONS From power valid MIN. TYP. 10 MAX.
