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 17 to 36MHz (fundamental resonant mode). ^: Denotes internal Pull-up *: Only one VDD pin needs to be connected BLOCK DIAGRAM XIN XOUT XTAL OSC VARICAP CLK OE VCON 47745 Fremont Blvd., Fremont, California 94538 Tel (510) 492-0990 Fax (510) 492-0991 www.phaselink.com Rev 09/08/06 Page 1 PLL500-17 Low Phase Noise VCXO (17MHz to 36MHz) DIE PAD LAYOUT 32 mil (812,986) DIE SPECIFICATIONS 8 1 XOUT XIN OE^ 7 39 mil 2 VDD VDD 6 3 VCON Name Value Size Reverse side Pad dimensions Thickness 39 x 32 mil GND 80 micron x 80 micron 10 mil CLK 5 4 GND DIE ID: PLL500-17: C500A0404-04A Y (0,0) X Note: ^ denotes internal pull up PACKAGE PIN and DIE PAD ASSIGNMENT Pin# Name Die Pad Position Type Description SOP-8 SOT23-6 X (µm) Y (µm) XIN 1 6 94.183 768.599 I Crystal input pin.
