PL500-17 PL500-17 PL500-17 Low Phase Noise VCXO (17MHz to 36MHz) FEATURES PIN CONFIGURATION VCXO output for the 17MHz to 36MHz range Low phase noise (-130dBc 10kHz offset at XIN 1 8 XOUT 35.328MHz) 2 7 VDD* OE LVCMOS output with OE tri-state control 17 to 36MHz fundamental crystal input 3 6 VCON VDD* Integrated high linearity variable capacitors GND 4 5 CLK 8mA drive capability at TTL output 150 ppm pull range, max 5% (typ.) linearity SOP-8L Low jitter (RMS): 2.5ps period jitter 2.5 to 3.3V operation Available in 8-Pin SOP, 6-pin SOT23 GREEN/ 1 6 XOUT XIN RoHS compliant packages, or Die GND 2 5 VDD 3 4 CLK VCON DESCRIPTION SOT23-6L The PL500-17 is a low cost, high performance and : Denotes internal Pu ll-up low phase noise VCXO for the 17 to 36MHz range, *: Only one VDD pin needs to be connected 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).
