The raw data mode configuration for the Si443x allows for the reception of any data pattern without the need to follow the recommended packet structure in the data sheet. A typical recommended packet structure is a preamble (01010…) sequence followed by a synchronization word and payload data. In raw data mode, the receiver does not search for a fixed preamble pattern. The receiver will track the incoming data as seen at the receiver input. Without deglitching the raw data mode, sensitivity is approximately 10dB worse than the standard but with deglitching running on the host MCU the sensitivity is only a 2-3 dB less than the standard mode. Further details can be found in AN463 application note.
