BB172X Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the RF traces as short as possible and use 50-ohm impedance matching to minimize signal reflections.
  • Use a reliable SPI interface with a clock frequency of 1-10 MHz. Ensure proper signal termination, and consider using a SPI bus buffer or repeater for longer distances.
  • The maximum transmit power of the BB172X is +20 dBm. You can adjust the transmit power by programming the PA_CTRL register (0x14) to set the desired power level.
  • Use the Frequency Hopping Spread Spectrum (FHSS) mode by setting the FHSS_EN bit in the MODE_CTRL register (0x10). Configure the hopping sequence using the FHSS_SEQ registers (0x18-0x1B).
  • A 26 MHz crystal oscillator is recommended for optimal performance. Ensure the oscillator is properly loaded and decoupled to minimize noise and jitter.
