FEATURES
VCXO output for the 48MHz to 100MHz range Low phase noise ( -130 dBc @ 10kHz offset at 48MHz) LVCMOS output 12 to 25MHz crystal input Integrated variable capacitors Selectable High Drive (30mA) or Standard Drive (10mA) output Wide pull range ( ± 250 ppm typ ) Low period jitter: 3.5ps RMS 3.3V operation Available in 8 -Pin SO P
DESCRIPTION
The PL502 -03 is a low cost, high performance and low phase noise VCXO for the 48 to 100MHz range, providing less than -130dBc at 10kHz offset at 48MHz. The very low j itter (3.5ps RMS period jitter) makes this chip ideal for applications requiring vol t- age co ntrolled frequency sources. Input crystal can range from 12 to 25MHz (fundamental resonant mode).

UNITS Crystal Resonator Frequency FXIN 12 25 MHz Crystal Loading Capacitance Ra ting CL (x ta l) 9.5 pF C0/C1 250 - ESR RS 30 Ω 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 no m- inal frequency at this load. If the crystal requires more load to be at nominal frequency, the additional load must be added externally. This ho wever may reduce the pull range. PACKAGE INFORM ATION (GREEN PACKAGE COMPL IANT) C L A E H D e B
