IDT XO LVDS CRYSTAL OSCILLATOR

XUL DATASHEET

DC Characteristics

* A pullup resistor from pin 6 (VDD) to pin 1 (E/D) enables output when pin 1 is left open.

AC Characteristics

Note: Inclusive of initial frequency accuracy, operating temperature range, supply variation, load variation, 3 times solder reflow, shock, vibration and 1 year aging at 25°C. We do not

recommend hand soldering the devices
