Description
The ICM7213 is a fully integrated micropower oscillator and
frequency divider with four buffered outputs suitable for inter-
facing 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 fre-
quencies including 2048Hz, 1024Hz, 34.133Hz, 16Hz, 1Hz,
and
1
/
60
Hz (plus composites).
The ICM7213 utilizes a very high speed low power metal
gate CMOS technology which uses 6.4V zeners between the
drains and sources of each transistor and also across the
supply terminals. Consequently, the ICM7213 is limited to a
6V maximum V
SUPPLY
, although a simple dropping network
can be used to extend the V
SUPPLY
range well above 6V
(See Figure 9).
