d) The input power difference between two subsequent high and low burst data.

e) 20% to 80% values

f) BRST_Det assert low when module receive “reset” signal, assert high when incoming burst is detected and latch to high state until next

“Reset” signal.

Digital RSSI Timing Specification

g) 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.

h) RSSI DDM working range is between -8 to -30 dBm. RSSI DDM accuracy is better than +/- 3dB for input power levels between -10 to -30 dBm,

the accuracy reduces to +/- 5dBm for power levels larger than -10dBm.
