Low Phase Noise VCXO (17MHz to 36MHz) FEATURES VCXO output for the 17MHz to 36MHz range Low phase noise (-130dBc @ 10kHz offset at 35.328MHz) LVCMOS output with OE tri-state control 17 to 36MHz fundamental crystal input Integrated high linearity variable capacitors 8mA drive capability at TTL output ±150 ppm pull range, max 5% (typ.) linearity Low jitter (RMS): 2.5ps period jitter 2.5 to 3.3V operation Available in 8-Pin SOP, 6-pin SOT23 GREEN/ RoHS compliant packages, or Die The PLL500-17 is a low cost, high performance and low phase 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 requiring voltage controlled frequency sources. Input crystal can range from 17 to 36MHz (fundamental resonant mode). 1 VDD* 2 VCON 3 GND 4 8 XOUT 7 OE^ 6 VDD* 5 CLK SOP-8L XOUT 1 GND 2 CLK 3 B17 LLL DESCRIPTION XIN P500-17 SC LLLLL PIN CONFIGURATION 6 XIN 5 VDD 4 VCON SOT23-6L ^: Denotes internal Pull-up *: Only one VDD pin needs to be connected BLOCK DIAGRAM XIN Xtal Osc CLK XOUT VCON Varicap OE 47745 Fremont Blvd., Fremont, California 94538 Tel (510) 492-0990 Fax (510) 492-0991 www.phaselink.com Rev 08/11/09 Page 1 Low Phase Noise VCXO (17MHz to 36MHz) DIE PAD LAYOUT DIE SPECIFICATIONS 32 mil (812,986) 8 1 XOUT XIN OE^ 7 39 mil 2 VDD VDD 6 3 VCON Name Value Size 39 x 32 mil Reverse side GND Pad dimensions 80 micron x 80 micron Thickness 10 mil CLK 5 4 GND DIE ID: C500xxxxxx 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 (m) Y (m) XIN 1 6 94.183 768.599 I Crystal input pin.
