ICM7213
One Second/One Minute Timebase Generator
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 6.4V
zeners between the drains and sources of each transistor and also across the supply terminals.
Consequently, the ICM7213 is limited to a 6V maximum VSUPPLY, although a simple dropping
network can be used to extend the VSUPPLY range well above 6V.

NOTE:
1. The ICM7213 uses dynamic dividers for high frequency division. As with any dynamic system, information is stored on very small nodal
capacitances instead of latches (static system), therefore there is a lower frequency of operation. Dynamic dividers are used to improve
the high frequency performance while at the same time significantly decreasing power consumption. At low V SUPPLY , operation at less
than 1MHz is possible.

Detailed Description
Control Inputs
The TEST input inhibits the 218 output and applies the 29
output to the 221 divider, thereby permitting a speedup of the
testing of the ÷ 60 section by a factor of 2048 times. This
also results in alternative output frequencies (see table).
Supply Voltage Considerations
The ICM7213 may be used to provide various precision
outputs with frequencies from 2048Hz to 1/60Hz using a
4.194304MHz quartz oscillator, and other output frequencies
may be obtained using other quartz crystal frequencies.
Since the ICM7213 uses dynamic high frequency dividers for
the initial frequency division there are limitations on the
VSUPPLY range depending on the oscillator frequency. If, for
example, a low frequency quartz crystal is selected, the
VSUPPLY should be selected in the center of the operating
window, or approximately 1.7V.
The WIDTH input may be used to change the pulse width of
OUT 4 from 125ms to 1s, or to change the state of OUT 4
from ON to OFF during INHIBIT.
See Figures 1 and 2 for output waveforms and effect of
control inputs.
VS +
The V SUPPLY to the ICM7213 may be derived from a high
voltage supply by using a simple resistor divider (if power is
of no concern), by using a series resistor for minimum
current consumption, or by means of a regulator.
EXAMPLE:
R1
f = 4.2MHz
8V ≤ V ≤ 12V (10 NOMINAL)
I1 ≈ 100µA
I2 ≈ 1mA
R2 ≈ 3kΩ
R2
R1 ≈ 6.8kΩ
Outputs
Pull up resistors will generally be required to interface with
other logic families. These resistors must be connected
between the various outputs and the positive power supply.

Oscillator Considerations
VS -
The oscillator consists of a CMOS inverter and a feedback
resistor whose value is dependent on the voltage at the
oscillator input and output terminals and the V SUPPLY .
Oscillator stabilities of approximately 0.1ppm per 0.1V variation are achievable with a nominal V SUPPLY of 5V and a single voltage dropping resistor. The crystal specifications are
shown in the Test Circuit.

It is recommended that the crystal load capacitance (CL) be
no greater than 22pF for a crystal having a series resistance
equal to or less than 75Ω, otherwise the output amplitude of
the oscillator may be too low to drive the divider reliably.
CBYPASS 0.01µF
It a very high quality oscillator is desired, it is recommended
that a quartz crystal be used having a tight tuning tolerance
±10ppm, a low series resistance (less than 25Ω), a low
motional capacitance of 5mpF and a load capacitance of
20pF. The fixed capacitor CIN should be 30pF and the oscillator tuning capacitor should range between approximately
16pF and 60pF.
