Data packet structure
An example data packet structure using theSi4022 Si4022 pair for data transmission. This packet structure is an example of how to use the
high efficiency FIFO mode at the receiver side:
AA
AA
AA
2D
D4
Databytes (received in the
FIFO of the receiver)
Preamble
Synchron pattern
D

The first 3 bytes compose a 24 bit length 01 pattern to let enough time for the clock recovery of the receiver to lock. The next two bytes
compose a 16 bit synchron pattern which is essential for the receivers FIFO to find the byte synchron in the received bit stream. The
synchron patters is followed by the payload. The first byte transmitted after the synchron pattern (D
0
in the picture above) will be the first
received byte in the FIFO.

Important: The bytes of the data stream should follow each other continuously, otherwise the clock recovery circuit of the receiver side
will be unable to track.
Further details of packet structures can be found in the IA ISM-UGSB1 software development kit manual.
