FEATURES
VCXO output for the 36MHz to 130 MHz range Low phase noise ( -148 dBc @ 10kHz of fset at 77.76 MHz). CMOS output with OE tri -state co ntrol. 36 to 130MHz fundamental crystal i nput. Integrated high linearity variable capac itors. 8mA drive cap ability at TTL output. +/- 150 ppm pull range, max 5% linea rity. Low jitter (RMS): 2.5ps period jitter. Single 2.5V ±10% or 3.3V ±10 power supply . Operating temperature range from -40C to +85 C Available in Die or Wafer form or SOP -8L or SOT23 -6L packa ging . DESCRIP TION The PL500 -37 is a low cost, high perfor mance and low phase noise VCXO for the 36 to 130MHz range, providing less than -148dBc at 10kHz offset at 77.76 MHz. The very low jitter (2.5 ps RMS period jitter) makes this chip i deal for applications r equiring voltage controlled frequency sources. The i nput crystal frequency can range from 36 to 130MHz (fundamental res onant mode).

If the crystal requires more load to be at nominal frequency, the additional load must be added externally. This ho wever may reduce the pull range. Note that the Cload values above are for the IC only, and do not include PCB parasitics. Crystal specifications for Cload include PCB paras itics.
