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 reference from commonly available high frequency quartz crystals 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 tuning purposes and the 17th stage output The MM5369 is available in an 8-lead dual-in-line epoxy package
