7.2.1 Overview
8168C-MCU Wireless-02/10
Table 7-4. O-QPSK Data Rate during PSDU
In Table 7-5 all PHY modes supported by the AT86RF212 are summarized with the
relevant setting for each bit of register TRX_CTRL_2. The “-“ (minus) character means
that the bit entry is not relevant for the particular PHY mode.
Table 7-5. Register 0x0C (TRX_CTRL_2) Bit Alignment
The AT86RF212 transceiver is split into an analog radio front-end and a digital domain,
see Figure 1-1. Referring to the receiver part of the analog domain, the differential RF
signal is amplified by a low noise amplifier (LNA) and split into quadrature signals by a
poly-phase filter (PPF). Two mixer circuits convert the quadrature signal down to an
intermediate frequency. Channel selectivity is achieved by an integrated band-pass
filter (BPF). The subsequent analog-to-digital converter (ADC) samples the receive
signal and additionally generates a digital RSSI signal, see section 6.4. The ADC output
is then further processed by the digital baseband receiver (RX BBP), which is part of
the digital domain.
