37 / 64 page  Page 36 ams Datasheet Document Feedback [v1-08] 2015-Sep-02 AS3933 − Detailed Description Figure 41: Antenna Damper Demodulator / Data Slicer As soon as the AS3933 detects successfully the frequency and the RSSI has got stable the channel selector compares the RSSI on all active channels and connects the channel amplifier which has the biggest RSSI to the demodulator. The channel selector needs 32 RF carrier periods to take this decision. The output signal (amplified LF carrier) of selected channel is connected to the input of the demodulator. The demodulator takes the signal to base-band and recovers two signals from the amplified RF signal; a fast and a slow envelop. Those two signals are fed to the data slicer, which is a comparator with programmable hysteresis. At the output of the data slicer are streamed the digital received bits. A concept block diagram is shown in the Figure 42. Channel Amplifier1 LC R LC R LC R Channel Amplifier2 Channel Amplifier1 LF1P LF2P LF3P LFN |
