Description
A crystal controlled, high frequency,
highly stable oscillator, compatible with
LVPECL Logic. The output can be dis-
abled to facilitate testing or combining
multiple clocks. Complementary out-
puts are standard. The device is con-
tained in a sub-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.
