Signal Detect Response Time
a) Signal Detect assert low when module receive “reset” signal, assert high when incoming burst is detected and latch to high state until next “Reset” signal.
Table 7 – Digital RSSI Timing Specification
RSSI Trigger Delay
RSSI Sampling Time
Internal I
Receiver Power DDM (RSSI) Error
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.
RSSI DDM working range is between -12 to -32 dBm. RSSI DDM accuracy is better than +/- 3dB for input power levels between -15 to -32
dBm, the accuracy reduces to +/- 5 dB for input power level larger between –12 to -15dBm. Testing condition is ONT ER 10dB.
