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.
