C MOS output. 1 2 to 25MHz crystal input. I ntegrated variable capacitors. S electable High Drive (30mA) or Standard Drive (10mA) output. W ide pull range (+/- 250 ppm typ.). L ow jitter (RMS): 3ps period (1 sigma). 3 .3V operation. A vailable in 8-Pin SOIC. P IN CONFIGURATION XOUT N/C VCON GND 1 2 3 4 8 7 6 5 XIN N/C VDD CLK PLL502-02 D ESCRIPTION T he PLL502-02 is a low cost, high performance, low phase noise VCXO, providing less than -130dBc at 10kHz offset in the 24MHz to 50MHz operating range. The very low jitter (3 ps RMS period jitter) makes this chip ideal for applications requiring voltage controlled frequency sources. Input crystal can range from 12 to 25MHz (fundamental resonant mode).

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. 4 7745 Fremont Blvd., Fremont, California 94538 Tel (510) 492-0990 Fax (510) 492-0991 w ww.phaselink.com R ev 12/14/05 Page 3 P LL502-02 L ow Phase Noise VCXO (24MHz to 50MHz) P ACKAGE INFORMATION 8 PIN SOIC (in mm) Symbol A A1 B C D E H L e Min.
