Instructions for Using the EM4095

1. Power Supply:

   • Ensure the supply voltage (VDD) is within the range of 2.7V to 5.5V.
   • Connect the VDD pin to the power source and GND to the ground.

2. Oscillator Configuration:

   • The EM4095 operates with an external oscillator in the range of 100 kHz to 150 kHz.
   • Connect the external oscillator to the XTAL1 and XTAL2 pins.

3. Data Communication:

   • The EM4095 supports a maximum data rate of 16 kbps.
   • Connect the data lines (TXD and RXD) to the microcontroller or other communication interfaces.

4. Modulation:

   • Use a modulation index (MI) between 10% and 20% for optimal performance.
   • The modulation can be achieved using the MOD pin.

5. Output Configuration:

   • The output voltage swing should be set between 0.5V and 3.3V.
   • Use appropriate resistors or voltage dividers to set the output level.

6. Capacitance Considerations:

   • The typical input capacitance (Cin) and output capacitance (Cout) are both around 10 pF.
   • Ensure that the external components do not significantly affect these values.

7. Temperature Range:

   • The EM4095 operates reliably within the temperature range of -40掳C to 85掳C.
   • For storage, ensure the device is kept within the range of -40掳C to 125掳C.

8. Testing and Troubleshooting:

   • Verify the supply voltage and connections before testing.
   • Use an oscilloscope to check the signal integrity on the data lines and oscillator pins.
   • Refer to the datasheet for detailed troubleshooting steps and additional information.
