Frequently Asked Questions
How do I select the right receiver model?
Select a TSOP with a carrier frequency that matches your remote control's required signal (e.g., 32 kHz or 36 kHz).
What is the maximum data rate support?
The modules support enhanced data rates up to 4000 bit/s and short burst transmissions (≥ 6 cycles/burst).
Are there specific installation requirements for optimal function?
Yes, it is recommended to use external resistors and capacitors (R+C) to suppress power supply disturbances.
Can I ignore the operating parameters before integrating this component?
No; all operating parameters must be validated by the customer for their specific application.
