Functional Description
A connection diagram for the MM5369 is shown in Figure 1
and a block diagram is shown in Figure 2
TIME BASE
A precision time base is provided by the interconnection of
a 3 579 545 Hz quartz crystal and the RC network shown in
between the OSC IN and the OSC OUT terminals Resistor
R1 is necessary to bias the inverter for class A amplifier
operation Capacitors C1 and C2 in series provide the paral-
lel load capacitance required for precise tuning of the quartz
crystal
The network shown provides
used with standard crystals trimmed for C
to better than

DIVIDER
A pulse is genertaed when divider stages 1 through 4 16
and 17 are in the correct state By mask options this pulse
is used to set or reset individual stages of the counter Fig-
programmed modulus
OUTPUTS
The Tuner Output is a buffered output at the crystal oscilla-
tor frequency This output is provided so that the crystal
frequency can be obtained without disturbing the crystal os-
cillator The Divide Output is the input frequency divided by
the mask programmed number Both outputs are push-pull
outputs
