DESCRIPTION

The PLL520-88 (PECL) and PLL520-89 (LVDS) are

VCXO ICs specifically designed to work with

fundamental crystals between 19MHz and 65MHz.

The selectable divide by two feature extends the

operation range from 9.5MHz to 65MHz. They

require very low current into the crystal resulting in

better overall stability. The OE logic feature allows

selection of enable high or enable low.
