ENABLE/DISABLE OPTIONS (E/N)

For the 32.768 kHz CXOMHT, Statek offers two

enable/disable options: E and N. The E-version has a Tri-

State output and stops oscillating internally when the output

is put into the high Z state. The N-version does not have

PIN 1 connected internally and so has no enable/disable

capability. The following table describes the Enable/Disable

option E.
