PL520-00

PL520-00 Low Phase Noise VCXO with multipliers (for 100-200MHz Fund Xtal) FE AT UR E S  100MHz to 200MHz Fundamental Mode Crystal.  Output range: 100 – 200MHz (no multiplication), 200 – 400MHz (2x multiplier), 400 – 700MHz (4x multiplier), or 800MHz – 1GHz (LVDS output only for 8x multiplier).  Available outputs: PECL, LVDS, or CMOS (High Drive (30mA) or Standard Drive (10mA) output).  Selectable OE Logic (enable high or enable low).  Integrated variable capacitors.  Supports 3.3V-Power Supply.  Available in die form.  Thickness 10 mil. DESCRIPTION PL520-00 is a VCXO IC specifically designed to pull high frequency fundamental crystals. 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.
