DESCRIPTION
The PLL500-15/16 is a low cost, high performance and low phase noise VCXO for the 1.0MHz 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).
