    Capacitors should be placed as close as possible to the pins and should have a low- resistance and low-inductance connection to ground to achieve the best performance. The crystal (XTAL), the two load capacitors (CX1, CX2), and the internal circuitry connected to pins XTAL1 and XTAL2 form the 16MHz crystal oscillator for the 2.4GHz transceiver.
