MM5369 17 Stage Oscillator Divider
General Description
The MM5369 is a CMOS integrated circuit with 17 binary
divider stages that can be used to generate a precise refer-
ence from commonly available high frequency quartz crys-
tals An internal pulse is generated by mask programming
the combinations of stages 1 through 4 16 and 17 to set or
reset the individual stages The MM5369 is advanced one
count on the positive transition of each clock pulse Two
buffered outputs are available the cyrstal frequency for tun-
ing purposes and the 17th stage output The MM5369 is
available in an 8-lead dual-in-line epoxy package
