Integrated high linearity variable capacitors. 12mA drive capability at TTL output. ± 150 ppm pull range, max 5% linearity. Low jitter (RMS): 2.5ps period jitter. 2.5V ~ 3.3V operation. Available in 8-Pin SOP, 6-pin SOT23 GREEN/ RoHS compliant packages, or DIE. PL500-15/16  PIN CONFIGURATION 6 CLK 5 VDD 4 XOUT SOT23-6L* ^: Denotes internal Pull-up *: SOT package offers single divider option only DESCRIPTION The PL500-15/16 is a low cost, high performance and low phase noise VCXO for the 1MHz to 18MHz range, providing less than -130dBc at 10kHz offset when using a 35.328MHz crystal. 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 1 6MHz to 36MHz (fundamental resonant mode).
