DESCRIPTION
The PLL620-80 is a XO IC specifically designed to
work with fundamental or 3rd OT crystals between
19MHz and 65MHz. The selectable divide by two
feature extends the operation range from 9.5MHz to
65MHz. It requires very low current into the crystal
resulting in better overall stability. The OE logic
feature allows selection of enable high or enable low.
Furthermore, it provides selectable CMOS, PECL or
LVDS outputs.
