P521-28 - Low Phase Noise PECL VCXO

Datasheet Summary

Description

P521-28 is a VCXO IC specifically designed to pull high frequency fundamental crystals.

Its internal varicaps allow an on chip frequency pulling, controlled by the VCON input.

The chip provides a low phase noise, low jitter PECL differential clock output.

Features

  • 100MHz to 200MHz Fundamental Mode Crystal.
  • Output range: 100MHz.
  • 200MHz.
  • Complementary PECL outputs.
  • Selectable OE Logic (enable high or enable low).
  • Integrated variable capacitors.
  • High pull linearity: < 5%.
  • +/- 125 ppm pull range www. DataSheet4U. com.
  • Supports 2.5V or 3.3V-Power Supply.
  • Available in die form.
  • Thickness 10 mil. DIE.
