MM5369 17 Stage OscillatorDivider

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
