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. 25 GND DESCRIPTION (1550,1475) 26 XOUT 62 mil    19MHz to 65MHz fundamental crystal input.
