7.7 Crystal Oscillator (XOSC) and Clock Output (CLKM)
The main features are:
16 MHz amplitude-controlled crystal oscillator
Fast settling time after leaving SLEEP state
Configurable trimming capacitance array
Configurable clock output (CLKM)
7.7.1 Overview
The crystal oscillator generates the reference frequency for the AT86RF212. All other
internally generated frequencies of the radio transceiver are derived from this
frequency. Therefore, the overall system performance is mainly determined by the
accuracy of crystal reference frequency. The external components of the crystal
oscillator should be selected carefully and the related board layout should be done with
caution (see section 3).
Two operating modes are supported. The recommended mode is the integrated
oscillator setup as described in Figure 7-15. Alternatively, a reference frequency can be
fed to the internal circuitry by using an external clock reference as shown in Figure 7-
16. The XOSC operating modes are configurable by register 0x12 (XOSC_CTRL).
