SOP-8L +/- 150 ppm pull range, max 5% linearity. Low jitter (RMS): 2.5ps period jitter. Single 2.5V 10% or 3.3V 10 power supply. VCON 1 6 CLK Operating temperature range from -40 C to +85 C GND 2 5 VDD Available in Die or Wafer form or SOP-8L or XIN 3 4 XOUT SOT23-6L packaging. SOT23-6L DESCRIPTION : Denotes internal Pull-up The PL500-37 is a low cost, high performance and low phase noise VCXO for the 36 to 130MHz range, providing less than -148dBc at 10kHz offset at 77.76MHz. The very low jitter (2.5 ps RMS period 32 mil (812,986) jitter) makes this chip ideal for applications requiring voltage controlled frequency sources. The input 8 crystal frequency can range from 36 to 130MHz XOUT 1 XIN (fundamental resonant mode).
