OUTLINE & DIMENSIONS
DESCRIPTION
The LXOAT oscillator is designed as a highly reliable crystal oscillator
able to withstand use in sever environments. The double hermetically
sealed package provides a permanently precise control of ouput
frequency.

ENABLE/DISABLE OPTIONS (E/T/N)
The LXOAT oscillator has these pin options available:
'E' (Enable), when pin 1 is LOW (0), the oscillator stops oscillating.
'T' (Tri-state), when pin 1 is LOW, the oscillator continues to run,
hoever, the output buffer amplifier stops functioning and output is in
a high impedance (Z) state.
