VSS=DVSS=0V, VDD=DVDD
Parameter
Set-up time after a sleep period
Time from full power to modulation
state
AM demodulation: Delay time from
input to output
Recovery time of reception after
antenna modulation
Note 1:
chain is ready to demodulate. The condition is of course that the amplitude on antenna has already reached its steady state
by that time (this depends on Q of antenna). See also Application Notes.
