DESCRIPTION
N/C
The ABX2038/39 is a family of XO IC’s specifically
designed to work with high frequency fundamental or
3rd OT crystals from 65MHz to 130MHz, with
GND
N/C
selectable PECL or LVDS outputs. They achieve
very low current into the crystal resulting in better
overall stability. Their very low jitter makes them
ideal for the most demanding timing requirements.
