6. Clocking
The SX1302 uses the 32 MHz clock source from its companion RF Front-end (for example, Semtech’s SX1250) to clock the
entire system. This clock is injected on pin 43 (RADIO_A_CLK_I). It is advised to use a GPS-precision TCXO (0.5 ppm), in order
to have a maximum “capture range” for the receiver, allowing lower precision reference clock, which are cheaper, on the
end-devices.
