Receiver Turn-On Timing

tional at turn-on is influenced by two factors. All receiver circuitry will be op-

erational 1 ms after the supply voltage reaches 2.2 Vdc. The BBOUT-

CMPIN coupling-capacitor is then DC stabilized in 4 time constants

power supply rise time is:

Receiver Wake-Up Timing

stant. When the operating temperature is limited to 60°C, the time

required to switch from sleep to receive is dramatically less for short sleep

times, as less charge leaks away from the BBOUT-CMPIN coupling

capacitor.

AGC Timing

The maximum AGC engage time tAGC is 5 µs after the reception

of a -30 dBm RF signal with a 1 µs envelope rise time.

Peak Detector Timing

The Peak Detector attack time constant is set by the value of the capacitor
