Output Enable/Disable for SEL481x (n/a for SEL4810):
A crystal controlled, high frequency,
highly stable oscillator, compatible with
LVPECL logic. The output can be disabled
to facilitate testing or combining with mul-
tiple clocks. The oscillator is packaged
in leadless SMD FR4 SO20 available in
four (4) or six (6) pad configurations (see
part number builder) and achieves excep-
tional frequency stability. This oscillator
is ideal for today's automated assembly
environments.
