PLL502-04
DESCRIPTION
The PLL502-04 is a low cost, high performance and low phase noise VCXO for the 96 to 200MHz range. The very low jitter (4ps RMS period jitter at 155.52MHz) makes this chip ideal for applications requiring voltage controlled frequency sources in CMOS. Input crystal can range from 12 to 25MHz (fundamental resonant mode).

Note: Crystal Loading rating: 9.5pF is the loading the crystal sees from the VCXO chip at VCON = 1.65V. 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.
