PL520-20 Low Phase Noise VCXO (for 100-200MHz Fundamental Crystals) FE AT UR E S  100MHz to 200MHz Fundamental Mode Crystals  Output range (no PLL):  100MHz – 200MHz (3.3V).  100MHz – 170MHz (2.5V).  Low Injection Power for crystal 50uW.  Complementary outputs: CMOS, PECL or LVDS.  Selectable OE Logic (enable high or enable low).  Integrated variable capacitors.  Supports 2.5V or 3.3V-Power Supply.  Available in die form.  Die thickness is 10 mil. DESCRIPTION PL520-20 is a VCXO IC specifically designed to pull high frequency fundamental crystals. Its design was optimized to tolerate higher limits of inter-electrode capacitance and bonding capacitance to improve yield. It achieves very low current into the crystal resulting in better overall stability. Its internal varicaps allow on-chip frequency pulling, controlled by the VC.
