Timing for data detection looks like the following. Two settings are possible: Continuous“ and
Single Shot“, which can be set by D5 and D6 in register 00H.
Frequ_Detect_Timing_continuous.wmf
Figure 3-29
Frequency Detection timing in continuous mode
Note 1:
Chip internal signal Sequencer enables data detection“ has a LOW to HIGH transition
about 2.6ms after RX is activated (see
Figure 2-15
).
Note 2:
The positive edge of the Window Count Complete“ signal latches the result of comparison
of the analog to digital converted RSSI voltage with TH3 (register 08H). A logic combination of this
output and the result of the comparison with single/double THx defines the internal signal
data_valid“.
Figure 3-29
shows that the logic is ready for the next conversion after 3 periods of the data signal.
Timing in Single Shot mode can be seen in the subsequent figure:
