The ABV2088 (PECL) and ABV2089 (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.

Input selection: Bond to GND to set to “0”, bond to VDD to set to “1”

No connection results to “default” setting through

internal pull-up/-down.

Logical states defined by PECL levels if

OE_SELECT is “1”

Logical states defined by CMOS levels if

OE_SELECT is “0”
