  • IF Frequency = 469000
  • Divisor = 125

Reading the frequency

  • I2C Address: 0xC7, 2 bytes
  • Frequency = Value * Divisor - IF Frequency
    • = (Value * 125) - 469000

eg.

  • 1249000 = (0x35,0xb0 * 125) - 469000

Writing the frequency

  • I2C Address: 0xC6, 2 bytes
  • Value = (Frequency + IF Frequency) / Divisor
    • = (Frequency + 469000) / 125

eg.

  • 0x35,0xb0 = (1249000 + 469000) / 125
