14-Stage Binary Ripple Counter With Oscillator
High–Performance Silicon–Gate CMOS
This device consists of 14 master–slave flip–flops and an oscillator with a frequency that is controlled either by a crystal or by an RC circuit connected externally. The output of each flip–flop feeds the next and the frequency at each output is half of that of the preceding one. The state of the counter advances on the negative–going edge of the Osc In. The active–high Reset is asynchronous and disables the oscillator to allow very low power consumption during stand–by operation.
State changes of the Q outputs do not occur simultaneously because of internal ripple delays. Therefore, decoded output signals are subject to decoding spikes and may have to be gated with Osc Out 2 of the HC4060A.
Output Drive Capability: 10 LSTTL Loads
Outputs Directly Interface to CMOS, NMOS, and TTL
Operating Voltage Range: 2 to 6 V
Low Input Current: 1 µA
High Noise Immunity Characteristic of CMOS Devices

This device contains protection circuitry to guard against damage due to high static voltages or electric fields. However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high–impedance cir­cuit. For proper operation, Vin and V
out
should be constrained to the
range GND v (Vin or V
out
) v VCC.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused outputs must be left open.

* For TA = 25°C and CL = 50 pF , typical propagation delay from Clock to other Q outputs may be calculated with the following equations:
VCC = 2.0 V: tP = [93.7 + 59.3 (n–1)] ns VCC = 4.5 V: tP = [30.25 + 14.6 (n–1)] ns VCC = 3.0 V: tP = [61.5+ 34.4 (n–1)] ns VCC = 6.0 V: tP = [24.4 + 12 (n–1)] ns

PIN DESCRIPTIONS
INPUTS Osc In (Pin 11)
Negative–edge triggering clock input. A high–to–low transition on this input advances the state of the counter. Osc In may be driven by an external clock source.
Reset (Pin 12)
Active–high reset. A high level applied to this input asynchronously resets the counter to its zero state (forcing all Q outputs low) and disables the oscillator.
OUTPUTS Q4—Q10, Q12–Q14 (Pins 7, 5, 4, 6, 13, 15, 1, 2, 3)
Active–high outputs. Each Qn output divides the Clock input frequency by 2N. The user should note the Q1, Q2, Q3 and Q11 are not available as outputs.
Osc Out 1, Osc Out 2 (Pins 9, 10)
Oscillator outputs. These pins are used in conjunction with Osc In and the external components to form an oscillator. When Osc In is being driven with an external clock source, Osc Out 1 and Osc Out 2 must be left open circuited. With the crystal oscillator configuration in Figure 6, Osc Out 2 must be left open circuited.

DESIGN PROCEDURES
The following procedure applies for oscillators operating below 2MHz where Z is a resistor R1. Above 2MHz, additional
impedance elements should be considered: C
out
and Ca of the amp, feedback resistor Rf, and amplifier phase shift error from
180°C.
Step 1: Calculate the equivalent series circuit of the crystal at the frequency of oscillation.

Reactance jXe should be positive, indicating that the crystal is operating as an inductive reactance at the oscillation frequency. The maximum Rs for the crystal should be used in the equation.
Step 2: Determine β, the attenuation, of the feedback network. For a closed-loop gain of 2,Aνβ = 2,β = 2/Aν where Aν is
the gain of the HC4060A amplifier.
Step 3: Determine the manufacturer’s loading capacitance. For example: A manufacturer may specify an external load
capacitance of 32pF at the required frequency.
Step 4: Determine the required Q of the system, and calculate R
load
, For example, a manufacturer specifies a crystal Q of
100,000. In-circuit Q is arbitrarily set at 20% below crystal Q or 80,000. Then R
load
= (2πfoLS/Q) – Rs where Ls and Rs are
crystal parameters.

( Eq 3 )
Here R = R
out
+ R1. R
out
is amp output resistance, R1 is Z. The C corresponding to XC is given by C = C1 + Cin.
Alternately , pick a value for R1 (i.e, let R1 = RS). Solve Equations 1 and 2 for C1 and C2. Use Equation 3 and the fact that
Q = 2πfoLs/(Rs + R
load
) to find in-circuit Q. If Q is not satisfactory pick another value for R1 and repeat the procedure.
CHOOSING R1
Power is dissipated in the effective series resistance of the crystal. The drive level specified by the crystal manufacturer is the maximum stress that a crystal can withstand without damage or excessive shift in frequency . R1 limits the drive level.
To verify that the maximum dc supply voltage does not overdrive the crystal, monitor the output frequency as a function of voltage at Osc Out 2 (Pin 9). The frequency should increase very slightly as the dc supply voltage is increased. An overdriven crystal will decrease in frequency or become unstable with an increase in supply voltage. The operating supply voltage must be reduced or R1 must be increased in value if the overdriven condition exists. The user should note that the oscillator start-up time is proportional to the value of R1.
SELECTING R
f
The feedback resistor, Rf, typically ranges up to 20MΩ. R
f
determines the gain and bandwidth of the amplifier. Proper bandwidth insures oscillation at the correct frequency plus roll-off to minimize gain at undesirable frequencies, such as
the first overtone. Rf must be large enough so as to not affect the phase of the feedback network in an appreciable manner.
