FEATURES
100MHz to 200MHz Fundamental Mode Crystal.
Output range: 100 200MHz (no multiplication).
Selectable OE logic.
Minimum bondwires required for VDD and GND.
Available outputs: PECL or LVDS.
Supports 3.3V-Power Supply.
Available in die form.
Thickness 10 mil.
DESCRIPTIONS
PLL620-21 is an XO IC specifically designed to work
with high frequency fundamental and third overtone
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. It offers a selectable OE logic and is ideal
for XO applications requiring LVDS or PECL output
levels at high frequencies.
