The fields are highly programmable and can be used to check any kind of pattern in a packet structure. The

general functions of the packet handler include the following:

ï®ï Detection/validation of Preamble quality in RX mode (PREAMBLE_VALID signal)

ï®ï Detection of Sync word in RX mode (SYNC_OK signal)

ï®ï Detection of valid packets in RX mode (PKT_VALID signal)

ï®ï Detection of CRC errors in RX mode (CRC_ERR signal)

ï®ï Data de-whitening and/or Manchester decoding (if enabled) in RX mode

ï®ï Match/Header checking in RX mode

ï®ï Storage of Data Field bytes into FIFO memory in RX mode

ï®ï Construction of Preamble field in TX mode

ï®ï Construction of Sync field in TX mode

ï®ï Construction of Data Field from FIFO memory in TX mode

ï®ï Construction of CRC field (if enabled) in TX mode

ï®ï Data whitening and/or Manchester encoding (if enabled) in TX mode

For details on how to configure the packet handler, see âAN626: Packet Handler Operation for Si446x RFICsâ.
