Instructions for TEF6638HW/03

1. Power Supply: Connect the supply voltage (VDD) within the specified range of 3.0V to 5.5V. Ensure stable power supply to avoid performance issues.

2. Standby Mode: To enter standby mode, set the appropriate control signal. The device consumes approximately 1.0mA in this mode.

3. Operating Mode: For full operational functionality, ensure the operating current does not exceed 200mA when powered at 5V.

4. RF Input Connection: Connect the RF input signal within the recommended level range (-10dBm to 10dBm) to prevent distortion or damage.

5. IF Output Utilization: The IF output level is typically -10dBm. Adjust any connected circuits accordingly to match this level.

6. Tuning: Tune the FM band between 76MHz and 108MHz using the provided tuning controls. Verify that the selected frequency is within the local legal broadcast range.

7. Performance Optimization:

   • Ensure image rejection is maintained at around 60dB for clear reception.
   • Maintain adjacent channel rejection at 70dB to minimize interference from nearby frequencies.
   • Achieve a stereo separation of at least 40dB for optimal stereo sound quality.

8. Installation and Handling: Handle the component with care to avoid static damage. Follow standard electronic assembly practices for soldering and installation.
