Frequency selection and power down control PDN1 PDN2 RFI2 Switch High High Low Low High Low High Low Open Open Closed Closed PDN1 and PDN2. The control logic is presented in table 1. Description Power down Antenna frequency 1 Antenna frequency 2, RFI2 capacitor connected in parallel with antenna Antenna frequency 2, RFI2 capacitor connected in parallel with antenna If frequency 1 is selected the RFI2 switch is open (non conductive). Antenna frequency is determined by antenna inductor LANT (see Typical Application on page 5), antenna capacitor CANT1 and parasitic capacitances related to antenna coil, inputs RFIP, RFIM and RFI2 (see Antenna Tuning Considerations below). Frequency 1 is the highest frequency of the two selected frequencies. If frequency 2 is selected then RFI2 switch is closed to connect CANT2 to pin RFIM in parallel with ferrite antenna and tune it to frequency 2. Frequency 2 is the lowest frequencies. frequency of the two selected It is recommended to switch the device to power down for at least 50ms before switching to another frequency. This guarantees fast startup in switching to another frequency. During minimum 50ms power down time the AGC capacitor voltage is completely pulled to VDD to initialize proper startup conditions for the AGC. Without the described proper fast startup control the startup time can be several minutes. With fast startup it is shortened typically to a few seconds. ANTENNA TUNING CONSIDERATIONS The ferrite bar antenna having inductance LANT and parasitic coil capacitance CCOIL is tuned to two reception frequencies f1 and f2 by parallel capacitors CANT1 and CANT2. The receiver input stage and internal antenna capacitor switches have capacitances CRFI and COFF2 which affect the resonance frequencies. COFF2 is switch capacitance when switch is open. When the antenna switch is closed the off capacitance is shorted by on resistance of the switch and it is effectively eliminated. Following relationships can be written for the two tuning frequencies. Frequency f1 (highest frequency): CTOT1~CCOIL+CANT1+CRFI+COFF2, assuming CANT2>>COFF2 1 f1 = 2π L ANT ⋅ CTOT 1 Frequency f2 (lowest frequency): CTOT2=CCOIL+CANT1+CANT2+CRFI 1 f2 = 2π L ANT ⋅ CTOT 2 4 (14) DA6181B.003 17 September, 2014 TYPICAL APPLICATION Note 1 VDD Note 5 CANT1 LANT CANT2 RFIP X2 Note 4 X1 Optional Control for AGC on/hold QO2 QO1 AON QI Demodulator & Comparator VDD AGC Amplifier OUT Receiver Output RFIM Ferrite Antenna RFI2 Power Supply/Biasing VDD VSS PDN1 PDN2 VBATTERY AGC DEC CDEC 47 nF CAGC 10 µF Power Down / VDD VDD Note 3 Fast Startup / Note 2 Frequency Selection Figure 1.

The reason why the crystal frequency is about 3 Hz higher than the signal frequency is that the crystal is operated without the loading capacitor. Without loading capacitor the actual resonance frequency is about 3 Hz lower than with load thus 77.503 kHz crystal resonates at 77.500 kHz when no loading capacitor is used. Table 2.

Large shunt capacitance mismatch between the two crystals can lead to nonideal filter characteristics and wide noise band-width. Effectively this means lower sensitivity performance. It should be noted that grounded crystal package has reduced shunt capacitance. This value is about 85% of floating crystal shunt capacitance. For example crystal with 1pF floating package shunt capacitance can have 0.85pF grounded package shunt capacitance. PCB traces of crystal and external compensation capacitance should be kept at minimum to minimize additional parasitic capacitance which can cause capacitance mismatching. When using MAS6181B1 it does not matter which of the two frequency crystals is connected to QO1 pin and which to QO2 pin.

The insulation resistance of these capacitors should be at minimum several 100 MΩ. Also probes with at least several 100 MΩ impedance should be used for voltage probing of the AGC and DEC pins to not disturb their operation. Tantalum capacitors have lower leakage than the electrolyte capacitors. In case of using electrolyte type AGC capacitor the capacitor voltage rating should be at least 25 V for sufficiently low leakage. The DEC capacitor can be low leakage chip capacitor since its capacitance value is small. It is recommended to connect both AGC and DEC capacitors to VDD (see application figures 1 and 2) although VSS connection is also possible. The VDD connection provides better supply noise immunity because the signals and AGC gain are referenced to VDD. Additionally leakage currents are minimized in this connection because in power down the AGC pin voltage is pulled to VDD (to minimum AGC gain) providing zero voltage over the AGC capacitor. 7 (14) DA6181B.003 17 September, 2014 TYPICAL APPLICATION (Continued) Note 3: Power Down / Fast Startup Control Both power down and fast startup is controlled using the PDN pin. The device is in power down (turned off) if PDN1 = PDN2 = VDD and in power up with other three PDN1 and PDN2 control bit combinations (see table 1 on page 4). Fast startup is triggered automatically when moving from power down to power up. The VDD must have been high before moving from power down to power up to guarantee proper operation of fast startup circuitry. Additionally the device should have been kept in power down state at least 50ms before power up. This guarantees that the AGC capacitor voltage has been completely pulled to VDD during power down. The startup time without proper fast startup control can be several minutes. With fast startup it is shortened typically to a few seconds. Note 4: Optional Control for AGC On/Hold AON control pin has internal pull up which turns AGC circuit on all the time if AON pin is left unconnected. Optionally AON control can be used to hold and release AGC circuit. Stepper motor drive of analog clock or watch can produce disturbing amount of noise which can shift the input amplifier gain to non optimal level. This can be avoided by controlling AGC hold (AON=VSS) during stepper motor drive periods and releasing AGC (AON=VDD) when motors are not driven. The AGC should be in hold only during disturbances and kept on other time released since due to leakage the AGC can still change slowly when in hold. Note 5: Ferrite Antenna The ferrite antenna converts the transmitted radio wave into a voltage signal. It has an important role in determining receiver performance. Recommended antenna impedance at resonance is around 100 kΩ. Low antenna impedance corresponds to low noise but often also to small signal amplitude. On the other hand high antenna impedance corresponds to high noise but also large signal. The optimum performance where signal-to-noise ratio is at maximum is achieved in between. The antenna should have also some selectivity for rejecting near signal band disturbances. This is determined by the antenna quality factor which should be approximately 100. Much higher quality factor antennas suffer from extensive tuning accuracy requirements and possible tuning drifts by the temperature. Antenna impedance Rant can be calculated using equation 1 where fres, L, Qant and C are resonance frequency fres, coil inductance, antenna quality factor and antenna tuning capacitor respectively. Antenna quality factor Qant is defined by ratio of resonance frequency fres and antenna bandwidth B (equation 2). Rant = 2π ⋅ f res ⋅ L ⋅ Qant = Qant = Qant 1 = 2π ⋅ f res ⋅ C 2π ⋅ B ⋅ C f res B Equation 1. Equation 2. Table 4 below presents some antenna suppliers for time signal application. Table 4.

Due to process variations the typical output pulse width can differ from these. Additionally the output pulse widths can vary even more depending on the receiving antenna signal strength versus noise and disturbance conditions. That is why it is important that the time signal decoding software has appropriate tolerance limits for managing the output pulse width variations successfully. The table 5 presents recommended software pulse width tolerance limits for recognizing pulses of different time signals. Table 5.
