ICM7213
One Second/One Minute Timebase Generator
Description
The ICM7213 is a fully integrated micropower oscillator and frequency divider with four buffered outputs suitable for interfacing with most logic families.
The power supply may be either a two battery stack (Ni-cad, alkaline, etc.
) or a regular power supply greater than 2V.
Depending upon the state of the WIDTH, INHIBIT, and TEST inputs, using a 4.
194304MHz crystal will produce a variety of output frequencies including 2048Hz, 1024Hz, 34.
133Hz, 16Hz, 1Hz, and 1/60Hz (plus composites).
The ICM7213 utilizes a very high speed low power metal gate
