**82384       Clock Generator and Reset Interface                  c86
***Notes:...
***Info:
The  M82384  combines  a   third-overtone  crystal  oscillator,  reset
synchronizing circuitry,  and address  status circuitry onto  a single
chip for easy timing and  control of Military 386 microprocessor-based
systems.

The M82384  contains a clock generator/driver that  provides two clock
signals for the Military microprocessor-based systems. The CLK2 signal
generated  by  the  M82384  meets  the  Military  386  processor  CLK2
requirements, and the CLK  signal indicates the Military 386 processor
phase. The  M82384 also  generates a synchronous  reset signal  from a
schmitt-trigger  reset input,  and provides  an Address  Status signal
that  has guaranteed setup  and hold  timing with  respect to  the CLK
output.
