Loadꢀ

-2V (all outputs require termination)

A high frequency, highly stable voltage-

controlled crystal oscillator, compatible

with LVPECL Logic. The output can be

disabled to facilitate testing or combin-

ingmultipleclocks.Complementaryout-

puts are standard.* The device is con-

tainedinasub-miniature, very low pro-

file, leadless ceramic SMD package

with 6 gold-plated contact pads. This

miniature oscillator is ideal for today's

automated assembly environments.
