REF1 and REF2 Blocks
The REF1 and REF2 blocks create midscale power-supply biasing points used internally to the AFE031. Each
reference divides its respective power-supply voltage in half with a precision resistive voltage divider. REF1
provides a PA_VS/2 voltage used for the PA, while REF2 provides an AVDD/2 voltage used for the Tx PGA, Tx
Filter, Rx PGA1, Rx Filter, and Rx PGA2. Each REF block has its output brought out to an external pin that can
be used for filtering and noise reduction. Figure 36 and Figure 37 show the proper connections of the external
noise-reducing capacitors. These capacitors are optional, but are recommended for best performance.
