Circuit Description
RAW Modes
In Raw mode, the
AX5043
does not perform any packet delimiting or byte synchronization. It
simply serializes transmit bytes and de-serializes the received bit-stream and groups it into bytes.
This mode is ideal for implementing legacy protocols in software.
Raw mode with preamble match is similar to raw mode. In this mode, however, the receiver does
not receive anything until it detects a user programmable bit pattern (called the preamble) in the
receive bit-stream. When it detects the preamble, it aligns the de-serialization to it.
The preamble can be between 4 and 32 bits long.
5.12. RX AGC and RSSI
The
AX5043
features a digital receiver signal strength indicator (RSSI). The RSSI can be read in
the RSSI register and has a resolution of 1 dB steps.
