PIN Description
IN1, IN2
A ferrite antenna is connected between IN 1 and IN 2. For high sensitivity, the Q factor of the antenna circuit
should be as high as possible. Please note that a high Q factor requires temperature compensation of the
resonant frequency in most cases. We recommend a Q factor between 40 and 150, depending on the
application. An optimal signal-to-noise ratio will be achieved by a resonator resistance of 40 kΩ to 100 kΩ.
QOUT, QIN , QC
In order to achieve a high selectivity, a crystal is connected between the Pins QOUT and QIN. It is used with
the serial resonant frequency according to the time-code transmitter and acts as a serial resonator. Up to 2
crystals can be connected parallel between QOUT and QIN. For one crystal, the given parallel capacitor of
the filter crystal (about 1.4 pF) is internally compensated so that the bandwidth of the filter is about 10 Hz.
For two crystals, an additional external capacitor with the value of about 1.4 pF has to be connected parallel
between QC and QIN. The impedance of QIN is high. Parasitic loads have to be avoided.
DEM
Demodulator output. To ensure the function, an external capacitor has to be connected at this output.
HLD
AGC hold mode: HLD high (VHLD = VCC) sets normal function, HLD low (VHLD = 0) holds for a short time the
AGC voltage. This can be used to prevent the AGC from peak voltages, created by e.g. a stepper motor
PK
Peak detector output. An external capacitor has to be connected to ensure the function of the AGC
regulation. The value of the capacitance influences the AGC regulation time.
NOTE: To realize a good regulation timing of the demodulator and the peak detector the value of the
capacitors at DEM and PK have to be changed for the different protocols.

VCC, GND
VCC and GND are the supply voltage inputs. The positive supplies have to be connected externally, and also
the ground pins.
To power down the circuitry it is recommended to use the PON input and not to switch the power supply.
Switching the power supply results in a long power up waiting time.
PON
If PON is connected to GND, the receiver will be activated. The setup time is typically 0.5 sec after applying
GND to this pin. If PON is connected to VCC, the receiver will switch to Power Down mode.
TCO, TCON
The serial signal of the time-code transmitter can be directly decoded by a micro controller. Details about the
time-code format of several transmitters are described separately. If TCO is connected, TCON must be open
or counterwise.

7 Design Hints for the Ferrite Antenna
7.1 Dimensioning of antenna circuit for different clock/watch applications
The bar antenna is a very critical device of the complete clock receiver. Observing some basic RF design
rules helps to avoid possible problems. The IC requires a resonant resistance of 40 kΩ to 100 kΩ. This can
be achieved by a variation of the L/C-relation in the antenna circuit. In order to achieve this resonant
resistance, we recommend to use antenna capacitors of a value between 2.2nF and 6.8nF. The optimum
value of the capacitor has to be specified respecting the concrete application needs and different boundary
conditions(ferrite material, type of antenna wire, available space for antenna coil).It is not easy to measure
such high resistances in the RF region. A more convenient way is to distinguish between the different
bandwidths of the antenna circuit and to calculate the resonant resistance afterwards.
Thus, the first step in designing the antenna circuit is to measure the bandwidth. Figure 12 shows an
example for the test circuit. The RF signal is coupled into the bar antenna by inductive means, e.g., a wire
loop. It can be measured by a simple oscilloscope using the 10:1 probe. The input capacitance of the probe,
typically about 10 pF, should be taken into consideration. By varying the frequency of the time signal
generator, the resonant frequency can be determined.

Scope

Wire loop
Cres
Figure 12.
At the point where the voltage of the RF signal at the probe drops by 3 dB, the two frequencies can then be
measured. The difference between these two frequencies is called the bandwidth BWA of the antenna circuit.
As the value of the capacitor Cres in the antenna circuit is known, it is easy to compute the resonant
resistance according to the following formula:
1
Rres=2 x π X BW X C
A
res
Where
Rres is the resonant resistance,
BWA is the measured bandwidth
Cres is the value of the capacitor in the antenna circuit (Farad).
If high inductance values and low capacitor values are used, the additional parasitic capacitance of the coil
must be considered. The Q value of the capacitor should be no problem if a high Q type is used. The Q
value of the coil differs more or less from the DC resistance of the wire. Skin effects can be observed but do
not dominate.
Therefore, it should not be a problem to achieve the recommended values of the resonant resistance. The
use of thicker wire increases the Q value and accordingly reduces bandwidth. This is advantageous in order
to improve reception in noisy areas. On the other hand temperature compensation of the resonant frequency
might become a problem if the bandwidth of the antenna circuit is low compared to the temperature variation
of the resonant frequency. Of course, the Q value can also be reduced by a parallel resistor.
Temperature compensation of the resonant frequency is a must if the clock is used at different temperatures.
Please ask your supplier of bar antenna material and of capacitors for specified values of the temperature
coefficient.

Furthermore, some critical parasitics have to be considered. These are shortened loops (e.g., in the ground
line of the PCB board) close to the antenna and undesired loops in the antenna circuit. Shortened loops
decrease the Q value of the circuit. They have the same effect like conducting plates close to the antenna.
To avoid undesired loops in the antenna circuit, it is recommended to mount the capacitor Cres as close as
possible to the antenna coil or to use a twisted wire for the antenna-coil connection. This twisted line is also
necessary to reduce feedback of noise from the microprocessor to the IC input. Long connection lines must
be shielded.
A final adjustment of the time-code receiver can be carried out by pushing the coil along the bar antenna.
7.2 Dimensioning of capacitor CDEM
The value of 22nF for capacitor CDEM as shown in chapter 9 and 10 represents the minimum value for
frequency of 77.5 kHz. For lower frequencies (40kHz, 60kHz) a minimum value of CDEM=47nF should be
used. For a better damping of noise and other interference it is recommended to double the values of CDEM,.
That means CDEM = 47nF for 77.5kHz and CDEM = 100nF for 40kHz and 60kHz. This optimization has to be
done according to each application.

Time-Code Format
The carrier amplitude is reduced by 10 dB at the
beginning of each second and is restored within
500 ms (binary one) or within 200 ms (binary
zero) or within 800 ms (position-identifier marker
or frame reference marker).
The time-code format consists of 1-minute time
frames. A time frame contains BCD-coded
information of minutes, hours, days and year. In
addition, there are 6 position-identifier markers
(P0 thru P5) and 1 frame-reference marker with
reduced carrier amplitude of 800 ms duration

17 Ozone Depleting Substances Policy Statement
It is the policy of C-MAX to
1. Meet all present and future national and international statutory requirements.
2. Regularly and continuously improve the performance of our products, processes, distribution and operating
systems with respect to their impact on the health and safety of our employees and the public, as well as
their impact on the environment.
It is particular concern to control or eliminate releases of those substances into the atmosphere, which are known
as ozone depleting substances (ODSs).
The Montreal Protocol (1987) and its London Amendments (1990) intend to severely restrict the use of ODSs and
forbid their use within the next ten years. Various national and international initiatives are pressing for an earlier
ban on these substances.
C-MAX has been able to use the policy of continuous improvements to eliminate the use of ODSs listed in following
documents.
1. Annex A,B and list of transitional substances of the Montreal Protocol and the London Amendments
respectively
2. Class I and II ozone depleting substances in the Clean Air Act Amendments of 1990 by the Environmental
Protection Agency (EPA) in the USA.
3. Council Decision 88/540/EEC and 91/690/EEC Annex A,B and C ( transitional substances) respectively.
C-MAX can certify that our semiconductor CME6005 is not manufactured with ozone depleting substances and do
not contain such substances.
