PL520-30

PL520-30 PECL and LVDS Low Phase Noise VCXO (for 65-130MHz Fund Xtal) FE AT UR E S  65MHz to 130MHz Fundamental Mode Crystals.  Output range (no PLL):  65MHz – 130MHz (3.3V).  65MHz – 105MHz (2.5V).  Low Injection Power for crystal 50uW.  Complementary outputs: PECL or LVDS.  Selectable OE Logic  Integrated variable capacitors.  Supports 2.5V or 3.3V-Power Supply.  Available in die form.  Thickness 10 mil. DESCRIPTION The PL520-30 is a VCXO IC specifically designed to pull frequency fundamental crystals from 65MHz to 130MHz, with selectable PECL or LVDS outputs and OE logic (enable high or enable low). Its design was optimized to tolerate higher limits of interelectrodes capacitance and bonding capacitance to improve yield. It achieves very low current into the crystal resulting in better overall stability. Its internal varicaps allow an on chip frequency pulling, controlled by the VCON input.
