DESCRIPTION
The PL500 -17 is a low cost, high perfor mance and low pha se noise VCXO for the 17 to 36MHz range, providing less than -130dBc at 10kHz offset at 35.328MHz. The very low jitter (2.5 ps RMS period jitter) makes this chip ideal for applications r equiring voltage co ntrolled frequency sources. Input crystal can range from 17 to 36MHz (fundamental res onant mode).
