Receiver Power DDM (RSSI) Error

+/- 3

dB

a)

RSSI_ACQ input signal rising edge will trigger RSSI sampling, and falling edge will trigger internal digital RSSI information written to I2C.

It is recommended that host shall not trigger RSSI_ACQ input again until RSSI data is valid in I2C from previous RSSI trigger.

b)

RSSI DDM working range is between -10 to -30 dBm. RSSI DDM accuracy is better than +/- 3dB for input power levels between -12 to -30

dBm, the accuracy reduces to +/- 5 dB for -10 to -12dBm.
