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.

Features

  • Guaranteed 2V Operation.
  • Very Low Current Consumption (Typ) . . . . 100µA at 3V.
  • All Outputs TTL Compatible.
  • On Chip Oscillator Feedback Resistor.
  • Oscillator Requires Only 3 External components: Fixed Capacitor, Trim Capacitor, and A Quartz Crystal.
  • Output Inhibit Function.
  • 4 Simultaneous Outputs: One Pulse/s, One Pulse/Min, 16Hz and Composite 1024 + 16 + 2Hz Outputs.
  • Test Speed-Up Provides Other Frequency Outputs Part Num.

TM NO RE December 2001 UCT PROD E MENT T E L PLACE E O B SO R D ENDE COMM 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 CMOS technology which uses 6.
