ASK modulation driver amplifier: ASK modulates the data and outputs it as an RD signal.

For types B and C, this is determined by the idling current (Ia) determined by Ra and parallel resistance of Ra + Rb. The degree of modulation is determined by the idling current (Iab). (Modulation is performed by switching pin 6 (DATA_SW) on and off.) For type A, the 100% modulation point is determined by the idling current (Iab) determined by the parallel resistance of Ra + Rb. (Modulation is performed by switching pin 4 (TYPE_SW) and pin 6 on and off at the same time.)

(3) Output level setting The output level is set by setting the two items (the input level and the idling current) described above and the damping resistor (Rd) between pins 22 and 23. Note that although an output amplitude (at pins 22 and 23) of about two times the VCC voltage can be acquired, if the output voltage limit is exceeded, a collision with the pin 5 voltage occurs and abnormal oscillation due to VCE saturation may occur. In such cases, changes to the antenna structure (VCC midpoint supply) and/or damping of the output level will be required.

Read amplifier (diode detector, bandpass filter, variable amplifier + fixed amplifier) : Data modulation from the RF signal (1) Level setting The input level is determined by voltage division by the capacitors connected between pins 21 and 22 and between pins 23 and 24 and the IC internal capacitance. However, note that the input dynamic range of pins 21 and 24 is the same as the VCC voltage. (2) Variable amplifier gain setting The gain is determined by the value of the resistor (Rg) connected between pin 19 and ground. Note that the range of values that may be used for Rg is from 4.7kΩ (minimum gain) to 100kΩ (maximum gain). 0 Bandpass Filter Characteristics 30 Variable Amplifier Gain Characteristics –5 25 Response [dB] – 10 20 – 15 Gain [dB] 100 1000 10000 15 – 20 10 – 25 5 – 30 10 0 0 10 20 30 40 50 60 70 80 90 100 Frequency [kHz] Pin 19 resistance (=Rg) [kΩ] No.A0641-11/14 LA7209V 3. Comparator: Used to provide 0V/5V pulse output of the demodulated data. (1) Setting the input level Signals from 10mVp-p to 2Vpp can be handled by using capacitor coupling to input the signal to pin 16. (2) Setting the output load resistance The load resistance is set so that the pin 15 current capacity is 2.2mA to 5mA. Note that this will be the range 2.2 kΩ to 1 kΩ when VCC = 5 V. 4. Variable threshold TAG detector: Detects tags in the communications area (1) Setting the input level The input level is determined by the resistor (Rg) connected between pin 19 and ground. Note however, that since the output level can also be modified at the same time by pins 17 and 18, the adjustment described in step (2) of the following item is required. (2) Setting the detection threshold level The built-in detector's threshold level can be changed by pin 14, and is set so that it can identify whether or not a TAG is present. * : The level goes to 500mV if the pin is left open. (3) Setting the detection (smoothing) capacitor The built-in detector's sensitivity is adjusted with pin 9. (Minimum capacitance : 10pF) (4) Setting the output load resistance Set the load resistance so that the pin 10 pull-in current is in the range 0.2mA to 0.5mA. Note that this will be the range 10kΩ to 24kΩ when VCC = 5 V. 5. Type switching: For IC card type switching • Low (0V to 1V) : Type B/C read/write communication is possible • High (2V to VCC) : Type A read/write communication is possible 6. Power save mode (muting) switching: Used for low-power mode control and driver amplifier output muting • Low (0V to 1V) : Normal operation ⇒ Read/write communication is possible • High (2V to VCC) : Power saving mode ⇒ Read/write communication is not possible No.A0641-12/14 LA7209V Application Circuit Example Antenna : 4Turn VCC1 5V 10μH VCC1 5V 10μH 10μF 47pF 1.0kΩ 47pF + VCC1 5V 100μH 10pF 68kΩ DATA OUT (to P13) VCC1 3V 2.2kΩ VCC1 3V 6.8kΩ 3.3kΩ 16 15 14 COMP TAG COMP OUT REF IN 13 GND 39pF 24 DET IN- 23 MOD OUT- 22 21 MOD DET OUT+ IN+ 20 VCC 19 EVR CTL GAIN 10~30dB 18 EVR OUT 17 AMP OUT AMP GAIN 30dB COMP LPF EVR MOD ON:TYPE-B/C REG CAR IN+ 2 2.7kΩ 100Ω 100Ω 100Ω CAR IN3 TYPE SW 4 15Ω DATA SW 6 MOD DATA IN 7 TAG DET 9 TAG DET COMP TAG TYPE OUT CTL 10 11 VCC1 5V 10kΩ PWR SAVE CTL 12 GND 1 MOD_E 5 4.7Ω 0.01μF REG 8 1μF OSC Data Command (to TP30) + 100pF TAG OUT (to P3) Reset CLT No.A0641-13/14 LA7209V SANYO Semiconductor Co.,Ltd. assumes no responsibility for equipment failures that result from using products at values that exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or other parameters) listed in products specifications of any and all SANYO Semiconductor Co.,Ltd. products described or contained herein.
